They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, a voltage detector and a phase compensation circuit plus a driver transistor. The output voltage of the LDO and detect voltage of the detector is selectable in 50mV increments within the range of 0.8V to 5.0V. With a low ON resistance driver transistor built-in, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The series provides options to the user to select from a variety of circuit features, such as detector monitoring, detector output logic, EN pin input logi c, and internal pull-up / down resistance (semi-custom). The IC's internal regulator circuit can be placed in stand-by mode via the EN function (XC6402C series). In the stand-by mode, power consumption is greatly reduced. The XC6402F series offers the option of a delay on the detector output: the delay time can be controlled by the use of an external capacitor. ■APPLICATIONS

The P-channel MOSFET, which is connected to the V ROUT pin, is then driven by the subsequent output signal. The output voltage at the V ROUT pin is controlled & stabilized by negative feedback. The current limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage regulator's internal circuitry can be shutdown via the EN pin's signal. <Detector Function with the XC6402 Series> The series' detector function monitors the voltage divided by resistors R3 & R4 which are connected to the VROUT pin or the VIN pin, as well as monitoring the voltage of the internal reference voltage source via the comparator. The VDSEN pin has options (please refer to the Selection Guide, item 2). A 'High' or 'Low' signal level can be output from the VDOUT pin when the VD pin voltage level goes below the detect voltage. The VD output logic has options (please refer to the Selection Guide, item 3). As V DOUT is an open-drain N-channel output, a pull-up resistor of about 220kΩ is needed to achieve a voltage output. Because of hysteresis at the detector function, output at the VDOUT pin will invert when the detect voltage level increases above the release voltage (105% of the detect voltage). For the XC6402C type, in stand-by, if a voltage of the recovery voltage is present at the V ROUT pin (from another power source), the VDOUT pin will be high impedance mode, and the pull up voltage will be output at V DOUT. By connecting the Cdelay pin to a capacitor (Cd), the XC6402F series can apply a delay time to V DOUT voltage when releasing voltage. The delay time can be calculated from the internal resistance, Rdelay (2MΩ TYP . fixed) and the value of Cd as per the following equation. Delay Time = Cdelay x Rdelay x 0.7 Delay Time Rdelay standard : 1.0 ~ 3.5MΩ TYP : 2.0MΩ <Low ESR Capacitors> With the XC6402 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase compensation circuit is built-in to the regulator. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) be connected as close as possible, between the output pin (VROUT) and the VSS pin. Please use an output capacitor (CL) with a capacitance, based on the chart below. We also suggest an input capacitor (C IN) of 1μF : this should be connected between VIN and VSS in order to stabilize input power source. Output Capacitor Corresponding Chart <Current Limiter, Short-Circuit Protection> The XC6402 series regulator offers a combination of current limit and circuit protection by means of a built-in fixed current limiter circuit and a foldback circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows.

XC6402C A ~ D High Active with pull-down resistor XC6402C E ~ K High Active with no pull-down resistor XC6402C L ~ P Low Active with pull-up resistor XC6402C R ~ U Low Active with no pull-up resistor ■OPERATIONAL EXPLANATION (Continued) <EN Pin> The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6402C series. In shutdown mode, output at the VROUT pin will be pulled down to the V SS level via R1 & R2. Note that as the XC6402*E to K types of the XC6402C series are 'High Active / No Pull-Down' and XC6402*R to U types of the XC6402C series are 'Active LOW / No Pull-Up', operations will become unstable with the EN pin open (See the chart below). We suggest that you use this IC with either a V IN voltage or a V SS voltage input at the EN pin. If this IC is used with the correct specifications for the EN pin, the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry if a voltage other than V IN or VSS is applied. ■NOTES ON USE 1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as C IN or CL to stabilize the operation.
