LND48XX

400mA Low Dropout Voltage Regulators

GENERAL DESCRIPTION

This series of fixed-voltage monolithic

micropower voltage regulators is designed for a

wide range of applications. This device is an

excellent choice for use in battery-powered

application. Furthermore, the quiescent current

increases only slightly at dropout, which

prolongs battery life.

This series of fixed-voltage regulators features

very low quiescent current(100mA Typ.) and

very low drop output voltage (Typ. 60mV at light

load and 420mV at 400mA). This includes a

tight initial tolerance of 0.5%typ. Extremely good

load and line regulation of 0.05% typ., and very

low output temperature coefficient. This series

of fixed-voltage regulators is offered in 3-pin TO-

220 package compatible with other fixed voltage

regulators. Adjust model is offered in 5-pin TO-

220 package and fixed model with shutdown

input is offered in 4-pin TO-220 package.

FEATURES

• 400mA output within 2% over

temperature

• Very low quiescent current

• Low dropout voltage (420mV Typ)

• Extremely tight load and line regulation

• Very low temperature coefficient

• Current and thermal limiting

• Unregulated DC input can withstand –

20V reverse battery and +60V positive

transients

• Direct replacement for SGS-Thomson-

L48XX Series, but has lower ground

current, higher accuracy of output

voltage and extremely tight load and

line regulation. The 5 pin version

(adjust model) and 4 pin version (fixed

model) have a shutdown input.
