DESCRIPTION
The UTC During normal operation of UTC L1131C, the dropout voltage is very low, and the response of line transient and load transient are very well. Inside each UTC L1131C, there’re many functions which can be seen in the block figure, for example, a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit. FEATURES
* Ultra Supply Current: 75µA(typ.) * Standby Mode: 0.1µA(typ.) * Very Low Dropout Voltage: 0.28V(typ.) @IOUT=150mA, VOUT=2.5V * Ripple Rejection: 70dB(typ.)@f=1kHz 60dB(typ.)@f=10kHz * Temperature-Drift Coefficient of Output Voltage: ±100ppm/°C(typ.) * Well Line Regulation: 0.02%/V(typ.) * Output Voltage Accuracy: ±2.0%(typ.) * Internal Fold Back Protection Circuit * CIN=COUT=1µF or more (Ceramic capacitors) are recommended to be used with this IC * Halogen Free ORDERING INFORMATION Ordering Number L1131CG-xx-AF5-R Note: Pin Assignment: I:VIN O:VOUT Package SOT-25 G:GND C:CE 1 I N:NC Pin...
