Dual LDO Regulators, Low ESR Cap. Compatible ■GENERAL DESCRIPTION The XC6401 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance features of the series includes low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. The XC6401 includes a reference voltage source, error am plifiers, driver transistors, current limiters and phase compensators internally. The XC6401’s current limiters' foldback circuit also operates as a short protect for the output current limiter. The output voltage for each regulator is set independent ly by laser trimming. Voltages are selectable in 50mV steps within a range of 0.8V to 5.0V. The XC6401 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of fr equencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The XC6401 series is available in the SOT-26W or USP-6B, USP-6C ‘chip-scale’ package. ■APPLICATIONS

■OPERATIONAL EXPLANATION ＜Output Voltage Control＞ The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFETs, which are connected to the V OUT1 and V OUT2 pins, are then driven by the subsequent output signal. The output voltages at the V OUT1 and V OUT2 pins are controlled and stab ilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, th e IC's internal circuitry can be shutdown via the EN pin's signal. ＜Low ESR Capacitors＞ With the XC6401 series, a stable output voltage is achiev able even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that output capacitors (CL1, CL2) is connected as close as possible to the output pins (V OUT1 and V OUT2) and the V SS pin. Please use an output capacitor with a capacitance value of at least 1μF. Also, please connect an input capacitor (CIN) of 1μF between the VIN pin and the VSS pin in order to ensure a stable power input. ＜Current Limiter, Short-Circuit Protection＞ The XC6401 series includes a combination of a fixed current limiter circuit & a foldback circuit which aid the operations of the current limiter and circuit protection. 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 voltag e, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows. ＜EN Pins＞ The IC's internal circuitry can be shutdown via the sign al from the EN1 and EN2 pins with the XC6401 series. In shutdown mode, output at the VOUT1 and VOUT2 pins will be pulled down to the VSS level via R11 & R12 and R21 & R22. The operational logic of the IC's EN1 and EN2 pins are selectabl e (please refer to the selection guide). Note that as the standard XC6401FF type's regulator 1 and 2 are both ' High Active/No Pull Down', operations will become unstable with the EN1 or EN2 pins open. Although the EN1 and EN2 pins are equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the EN1 and EN2 pins input current will increase when the IC is in operation. We suggest that you use this IC with either a V IN voltage or a V SS voltage input at the EN1 and EN2 pins. If this IC is used with the correct specifications fo r the EN1 and EN2 pins, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry. 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 keep the resistance low between V IN and VSS wiring in particular. 3. Please wire the input capacitor (C IN) and the output capacitors (CL1, CL2) as close to the IC as possible. ■NOTES ON USE VR1 each circuit ON/OFF Control Error Amp1 Voltage Reference ON/OFF Control Current Limit VR2 each circuit Error Amp2 Current Limit EN1 VIN VSS EN2 VOUT1 VOUT2 R11 R12 R21 R22
