LP2985AIM5-3.3/NOPB Datasheet PDF - TI

The LP2985AIM5-3.3/NOPB is a fixed output, micropower low noise ultra low dropout (LDO) regulator in 5 pin SOT-23 package. This regulator is designed for use with very low ESR output capacitors. Using an optimized VIP (Vertically Integrated PNP) process, the LP2985AIM5-3.3/NOPB delivers unequalled performance for all battery powered designs. This regulator provides 1% tolerance precision output voltage with only 75µA quiescent current at 1mA load and 850µA at 150mA load. By adding a 10nF bypass capacitor, the output noise can be reduced to 30µVrms in a 30KHz bandwidth. The LP2985AIM5-3.3 is designed to work with ceramic output capacitor with equivalent series resistance (ESR) as low as 5mohm.

● Fixed output voltage is 3.3V

● Output current is 150mA

● Dropout voltage is 280mV at 150mA load current

● Input voltage range from 2.5V to 16V

● Less than 1µA quiescent current when shut down

● Low ground pin current at all loads

● Output voltage accuracy is 1% (A grade)

● High peak current capability

● Overtemperature and overcurrent protection

● Junction temperature range from -40°C to 125°C

●This device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
