BCD AS78L15R 100ma positive voltage regulator Datasheet

Preliminary Datasheet
100mA POSITIVE VOLTAGE REGULATOR
AS78LXX
General Description
Features
The AS78LXX series are three terminal positive regulators designed for a wide variety of applications
including local, on-card regulation.
·
·
·
This series of regulators are complete with internal
current limiting, thermal shutdown protection, and
safe-area compensation which make them virtually
immune from output overload. If adequate heat sinking
are provided, these regulators can deliver output currents up to 100mA.
·
·
·
·
Output Current up to 100mA
Fixed Output Voltages of 5V, 12V, 15V, 18V and
24V
Output Voltage Accuracy of ±5% over the Full
Temperature Range
Internal Short Circuit Current Limiting
Internal Thermal Overload Protection
No External Components
Output Transistor Safe-area Protection
Applications
The AS78LXX series are available in TO-92 and SOT89-3 packages.
