EZ55Z3L
0.25 Amp Positive
Voltage Regulators
POWER MANAGEMENT
Description
Features
The EZ55Z3L voltage regulators are monolithic integrated
circuits designed for use in applications requiring a well
regulated positive output voltage with low input-to-
output differential voltage requirements.
u External capacitor not required for stability
u Low dropout performance
u Five fixed voltage options: 3.3V, 5V, 9V, 12V, 24V
u Adjustable output down to 1.25V
u Line regulation typically 0.015%
u Load regulation typically 0.1%
Outstanding features include full power usage up to
250mA of load current, internal current limiting and
thermal shutdown. Safe area protection on the die is
also included, providing protection of the series pass
transistor under most operating conditions. TO-92 and
SOT-223 packages are available for cost effective
applications.
