LDLN015

150 mA - ultra low noise - high PSRR linear voltage regulator IC

Datasheet

production data

• Internal current and thermal limit

• Package DFN6 (2 x 2 mm)

• Temperature range: - 40 °C to 125 °C

Description

The LDLN015 is an ultra low noise linear

regulator which provides 150 mA maximum

current from an input voltage ranging from 2.1 V

to 5.5 V with a typical dropout voltage of 86 mV.

With its 6.3 µV_RMSnoise value in a band from 10

Hz to 100 kHz, the LDLN015 provides a very

clean output suitable for ultra sensitive loads. It is

stable with ceramic capacitors. High PSRR, low

quiescent current and very low noise features

make it suitable for low power battery powered

applications. Power supply rejection is higher

than 90 dB at low frequencies and starts to roll off

at 10 kHz. The enable logic control function puts

the LDLN015 into shutdown mode allowing a total

current consumption lower than 1 µA. The device

also includes a short-circuit constant current

limiting and thermal protection. Typical

DFN6 (2 x 2 mm)

Features

• Ultra low noise: 6.3 µV_RMSfrom 10 Hz to

100 kHz

• Input voltage from 2.1 to 5.5 V

• Very low quiescent current (35 µA typ. at no

load, 70 µA typ. at 150 mA load; 2 µA max. in

off mode)

• Output voltage tolerance: ± 1% at 25 °C

• 150 mA guaranteed output current

• Wide range of output voltage from 0.8 V to

3.3 V with 100 mV step

applications are noise sensitive loads like ADC,

VCO in mobile phones, and personal digital

assistants (PDAs).

• Logic-controlled electronic shutdown

• Compatible with ceramic capacitor

(C_OUT= 0.47 µF)

• No bypass capacitor is required
