AIC1721 Datasheet 3-pin Low Dropout Linear Regulator

Manufacturer: Analog Intergrations Corporation

Overview: AIC1721/1721D 3-pin Low Dropout Linear Regulator.

General Description

The AIC1721/1721D is the enhanced CMOS version of the LP2950.

The superior characteristics of the AIC1721/1721D include zero base current loss, very low dropout voltage, and 1% accuracy output voltage.

Typica-l ground current remains approximately 55µA, from no load to maximum loading conditions.

Key Features

  • Low Dropout Voltage of 130mV at 100mA Output Current (5V Output Version). Guaranteed 150mA/300mA Output Current. Internal 1.3Ω P-MOSFET Draws no Base Current. Low Ground Current at 55µA. 1% Accuracy Output Voltage of 3.3V/5V. Input Voltage Range up to 12V (5V Output Version). Extremely Tight Load and Line Regulation. Fast Transient Response. Needs only 1µF for Stability. Current and Thermal Limiting.
