These devices feature very low quiescent current of 0.3mA or less when supplying 10mA loads. This unique characteristic and the extremely low input-output differential required for proper regulation (0.25V for output currents of 100mA) make the AMS3102 ideal to use for standby power systems. Internal circuitry of AMS3102 is protected from input fault conditions caused by reverse battery in stallation or input voltages that exceed maximum rated input voltage. During line transients, such as load dum p (40V) when the input voltage to the regulator can momentarily exceed the speci fied maximum operating voltage, the regul ator will automatically shut down to protect both internal circuits and the lo ad. The AMS3102 series also includes intern al current limiting, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion. The AMS3102 is offered in the 3-pin TO-92 package, SOT-89, 3 lead SOT-23, 5 lead SOT-23 and 8 lead SOIC packages. The device is provided with On/Off pin in SOT-23 5L and in 8 lead SOIC package.

Dropout Voltage: The input-output voltage differential at which the circuit stops to regulate against further reduction in input voltage. Measured when the output voltage has dropped 100mV from the nominal voltage obtained at 1V input, dropout voltage is dependent upon load current and junction temperature. Input Voltage: The DC voltage applied to the input terminal with respect to ground. Input-Output Di fferential: The voltage difference between the unregulated input voltage and the regulated output voltage for which the regulator will regulate. Line Regulation: The change in output voltage for a change in the input voltage. The line regulation is measured under conditions of low dissipation or by using lo w duty cy cle pulse testing such that the average chip temperature is not significantly affected. Load Regulation: The change in output voltage for a change in load current at constant chip temperature. Long term stability : Output voltage stability under accelerated life-test conditions after 1000 hour s with maximum rated voltage and junction temperature. Output Noise Voltage : The rms AC voltage at the output, with constant load and no input ripple, measured over a specified frequency range. Quiescent Cu rrent: That part of the positive input current that does not contribute to the positive load current. The regulator ground lead current. Ripple Rej ection: The ratio of the peak-to –peak input ripple voltage to the peak-to-peak output ripple voltage at specified frequency. Temperature Stability of VO: The percentage change in output voltage for a thermal variation from room tem perature to either temperature extreme. External capacitor The AMS3102 series require an output capacitor of 2.2 µF or greater to ensure device stability . Without the capacitor the device may oscillate. Most type of tantalum or electroly tic capacitor can be us ed in the applications. A critical characteris tic of the capacitors is an ES R value of 5 Ω or less and a resonant frequency above 500kHz. The value of this capacitor can be increased without limits. For higher loads, the value of the capacitor should be increased, specially when the output voltage is set for 2.5V or less. The AMS3102 lowest fixed output voltage value is 2.0V. Typical application circuit (adjustable output) ADJ + AMS3102 ADJUSTABLE GND 22µF 10µF OUT OFF ON ON/OFF R1 28k VOUT VIN 100k Minimum Load In circuits using the fixed output voltage versions, minimum load is not required. For circuits usi ng the adjus table device, the value of R1 and R2 should be chosen such, that a current of approximately 40 µA flows through the network. The reference voltage (1.235V) is measured between the adjust pin and V OUT. The output voltage can be set by the two resistors R1 and R2 using the following equation: ⎛ += R1 R2R1VV REFO The value of R1 is recommended to be between 25k Ω to 30 k Ω, and the value of R2 will set the output voltage.
