LDR1833

LDR2533

Very low drop dual voltage regulator

Features

■ Output current 1 up to 500 mA

■ Output current 2 up to 1.0 A

■ Low dropout voltage 1 (0.3 V @ I = 500 mA)

■ Low dropout voltage 2 (0.4 V @ I = 1 A)

■ Very low supply current (typ. 50 µA in OFF

mode, 1.6 mA max in ON mode)

PPAK

■ Logic-controlled electronic shutdown output

voltage availability for each regulator: 1.8 V,

2.5 V, 3.3 V

■ Internal current and thermal limit

■ Stable with low value (min. 4.7 µF) and low

ESR output capacitors

■ Supply voltage rejection: 70 dB (typ.)

■ Temperature range (- 40 °C to 125 °C)

Description

The LDR1833, LDR2533 is a very low drop dual

voltage regulator available in PPAK. The very low

drop-voltage (0.5 V) and the very low supply

current make it particularly suitable for low noise

and low power applications such as PDA,

Microdrive and other data storage applications

while the used high voltage technology makes this

device suitable for consumer applications such as

Monitors and Set-top-box. For each V a

shutdown logic control function is available (TTL

compatible) to decrease the total power

consumption.
