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.
