SC1565

Very Low Dropout

1.5 Amp Regulator With Enable

POWER MANAGEMENT

Description

Features

The SC1565 is a high performance positive voltage

regulator designed for use in applications requiring very

low dropout voltage at up to 1.5 Amps. Since it has

superior dropout characteristics compared to regular

LDOs, it can be used to supply 2.5V on motherboards or

2.8V on peripheral cards from the 3.3V supply thus

allowing the elimination of costly heatsinks. Additionally,

the 5-lead TO-220/TO-263 and SO-8 versions have an

enable pin to further reduce power dissipation while shut

down. The SC1565 provides excellent regulation over

variations in line, load and temperature.

350mV dropout @ 1.5A

Adjustable output from 1.2V to 4.8V⁽¹⁾

2.5V and 1.8V options (adjustable externally

using resistors)⁽¹⁾

Over current and over temperature protection

Enable pin⁽¹⁾

10µA quiescent current in shutdown⁽¹⁾

Low reverse leakage (output to input)

Surface mount and through-hole packages

Full industrial temperature range

TO-220, TO-263, SOT-223 and SO-8 Packages

Note:

The SC1565 is available in SO-8, 3-lead SOT-223, 3 and

5 lead TO-220 and 3 and 5 lead TO-263 packages. Three

lead packages are available with 1.8V and 2.5V fixed

output options only. The SO-8, TO-220-5 and TO-263-5

are available with 1.8V and 2.5V internally preset

outputs that are also adjustable using external resistors.

(1) SO-8, TO-220-5 and TO-263-5 packages only.
