LP3996

Dual Linear Regulator with 300mA and 150mA Outputs

and Power-On-Reset

General Description

Key Specifications

n Input Voltage Range

2.0V to 6.0V

210mV at 300mA

35µA

The LP3996 is a dual low dropout regulator with power-on-

reset circuit. The first regulator can source 150mA, while the

second is capable of sourcing 300mA and has a power-on-

reset function included.

n Low Dropout Voltage

n Ultra-Low I_Q(enabled)

n Virtually Zero I_Q(disabled)

10nA

The LP3996 provides 1.5% accuracy requiring an ultra low

quiescent current of 35µA. Separate enable pins allow each

output of the LP3996 to be shut down, drawing virtually zero

current.

Package

All available in Lead Free option.

The LP3996 is designed to be stable with small footprint

ceramic capacitors down to 1µF. An external capacitor may

be used to set the POR delay time as required.

10 pin LLP 3mm x 3mm

For other package options contact your NSC sales office.

The LP3996 is available in fixed output voltages and comes

in a 10 pin, 3mm x 3mm, LLP package. .

Applications

n Cellular Handsets

n PDA’s

Features

n Wireless Network Adaptors

n 2 LDO Outputs with Independent Enable

n 1.5% Accuracy at Room Temperature, 3% over

Temperature

n Power-On-Reset Function with Adjustable Delay

n Thermal Shutdown Protection

n Stable with Ceramic Capacitors
