SNVS160F –OCTOBER 2001–REVISED OCTOBER 2013

LP3984 Micropower 150 mA Ultra Low-Dropout CMOS Voltage Regulator in Subminiature

4-I/O DSBGA Package

Check for Samples: LP3984

FEATURES

DESCRIPTION

The LP3984 is designed for portable and wireless

applications with demanding performance and space

requirements.

•

Miniature 4-I/O DSBGA or SOT-23-5 Package

Logic controlled enable

•

Stable with Tantalum Capacitors

1 µF Tantalum Output Capacitor

Fast Turn-On

The LP3984's performance is optimized for battery

powered systems to deliver extremely low dropout

voltage and low quiescent current. Regulator ground

current increases only slightly in dropout, further

prolonging the battery life.

Thermal Shutdown and Short-Circuit Current

Limit

Power supply rejection is better than 60 dB at low

frequencies and starts to roll off at 10 kHz. High

power supply rejection is maintained down to low

input voltage levels common to battery operated

circuits.

KEY SPECIFICATIONS

•

2.5 to 6.0V Input Range

150 mA Output

60 dB PSRR at 1 kHz, 40 dB at 10 kHz @ 3.1V_IN

≤ 1.2 µA Quiescent Current when Shut Down

Fast Turn-On Time: 20 µs (typ.)

75 mV typ Dropout with 150 mA Load

The device is ideal for mobile phone and similar

battery powered wireless applications. It provides up

to 150 mA from a 2.5V to 6V input. The LP3984

consumes less than 1.2 µA in disable mode and has

fast turn-on time less than 20 µs.

−40 to +125°C Junction Temperature Range for

The LP3984 is available in a 4-bump DSBGA and 5-

pin SOT-23 packages. Performance is specified for

−40°C to +125°C temperature range and is available

in 1.5V, 1.8V, 2.9V and 3.1V output voltages. For

other output voltage options from 1.5V to 3.5V,

please contact TI sales office.
