AIC1721/1721D

3-pin Low Dropout Linear Regulator

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ Low Dropout Voltage of 130mV at 100mA Output

Current (5V Output Version).

The AIC1721/1721D is the enhanced CMOS

version of the LP2950. The superior

ꢀ 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.

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. Dropout

voltage at 100mA output current is significantly

lower than its bipolar counterpart: 130mV for the

AIC1721-5/1721D-5, and 180mV for the

AIC1721/ 1721D. Output current limiting and

thermal limiting are built in to provide maximal

protection to the AIC1721/ 1721D against fault

conditions.

ꢀ Current and Thermal Limiting.

ꢀ APPLICATIONS

ꢀ Voltage Regulator for LAN Cards.

ꢀ Wireless Communication Systems.

ꢀ Battery Powered Systems.

While pin-to-pin compatible with the LP2950 and

the industry industry standard 78XX series of

voltage regulators, the AIC1721/1721D comes in

the popular3-pin SOT-89 or TO-92 packages.
