3 Description

Operating from a minimum input voltage of 1.65 V,

the LP3991 LDO has been designed to provide fixed

stable output voltages for load currents up to 300 mA.

This device is suitable where accurate low voltages

are required from low input voltage sources and is

therefore suitable for post regulation of switched

mode regulators. In such applications, significant

improvements in performance and EMI can be

realized, with little reduction in overall efficiency. The

LP3991 provides fixed outputs as low as 1.2 V from a

wide input range from 1.65 V to 4 V Using the enable

(EN) pin, the device may be controlled to provide a

shutdown state, in which negligible supply current is

drawn.

The LP3991 is designed to be stable with spacesaving

ceramic capacitors as small as 0402 case

size.

Performance is specified for a –40°C to +125°C

junction temperature range. For output voltage

options, contact your local Texas Instruments sales

office.
