SC1202

600mA Low Dropout Positive

Voltage Regulator

POWER MANAGEMENT

Description

Features

The SC1202 series of high performance positive voltage

regulators are designed for use in applications requiring

low dropout performance at full rated current.

Additionally, the SC1202 series provides excellent

regulation over variations due to line, load and

temperature.

Low dropout performance, 1.3V max.

Full current rating over line and temperature

Fast transient response

±2% total output regulation over line, load

and temperature

Adjust pin current max. 90µA over temperature

Adjustable or fixed output voltages

Line regulation 0.2% max.

Outstanding features include low dropout performance

at rated current, fast transient response, internal

current limiting and thermal shutdown protection of the

output device. The SC1202 series are three terminal

regulators available in the surface mount SOT-223

package.

Load regulation 0.4% max.

SOT-223 package

Applications

Low voltage microcontrollers

Microprocessor I/O supplies

5V to 3.3V conversion for memory, ASIC, custom

circuits, etc.
