AATI Announces New PowerLinear Product Family


New Products Apr 03, 2002 by Jeff Shepard

Advanced Analogic Technologies Inc. (Sunnyvale, CA) announced its new five-device family of power management ICs, which offer low power and low noise that extend the battery life of next-generation portable, communications and computer systems. The PowerLinear product line consists of the NanoPower and MicroPower families.

For applications that require maximum battery life, the Nanopower LDO linear regulators feature a low 1.1µA, typical, quiescent current. The dropout voltage is also low at 200mV, typical, at a guaranteed 150mA output current. All three devices feature output short-circuit and over-current protection. The entire NanoPower product line is rated across a -40 to +85 degrees C temperature range.

For noise-sensitive RF, communications and mobile designs, the MicroPower LDOs offer minimal noise, fast transient response and high power supply ripple rejection. The AAT3215 features a low 140mV dropout voltage with a low quiescent current of 95µA, typical, at full output; and a high power supply ripple rejection of 70dB at 1kHz and 50dB at 10kHz. The AAT3236 delivers a continuous 300mA output load current and supports current peaks of short duration up to 500mA. The device’s low dropout voltage is 300mV, typical, at the full 300mA output load current. Quiescent current is 100µA, typical. The AAT3236 delivers a high power supply ripple rejection of 70dB at 1kHz and 50dB at 10kHz.

All three NanoPower LDOs come in compact SOT23 or SC70JW packages. The AAT3221/2 are available in five-pin SOT23 or eight-pin SC70JW packages while the AAT3220 is available in a three-pin SOT23, eight-pin SC70JW and a SOT89 package. The two MicroPower LDOs come in five-pin SOT23 or eight-pin SC70JW packages. Both are available in a variety of factory-programmed operating voltages ranging from 2.5V to 3.5V.

In 1,000-unit quantities, the AAT3215 is $0.36, the AAT3220 is $0.29, the AAT3221/2 is $0.29, and the AAT3236 is $0.54. All devices are available now.
