LP3982S

75dB High PSRR 42μV Low Noise LDO

General Description

Features

The LP3982S family are high performance low dropout

(LDO) voltage regulators with high PSRR, fast transient

⚫

Wide Input Voltage Range: 2.2V to 5.5V

Fixed Output Voltage: 1.2V, 1.8V, 2.8V, 3.3V

response, high accuracy, and low output noise. The

devices with advanced CMOS process are suitable for

many applications that require regulated supplies of up

to 300mA load current.

Maximum Load Current: 300mA

High PSRR at Full Frequency Range:

75dB@1kHz

60dB@10kHz

50dB@100kHz

The family include standard fixed output voltages of

1.2V, 1.8V, 2.8V, and 3.3V. The devices are stable with

a 1.0μF~10μF ceramic output capacitor. The devices

are protected from short circuit by a current limit

function and from over-heating by a thermal overload

protection.

⚫

Low Noise: 42μVrms, V_OUT=2.8V

Low Quiescent Current: 58μA typical

Low Dropout Voltage:

66mV @ 100mA Load, V_OUT=2.8V

200mV @ 300mA Load, V_OUT=2.8V

The devices are available in standard DFN-4

(1mmx1mm) and SOT23-5 packages.

⚫

Output Voltage Accuracy: ±1% @ 1mA

Short Circuit Current Limit: 110mA
