TDA8138 (5.1V+12V regulator with Disable and Reset)
(1) General Description
The TDA8138 is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of
5.1V and 12V at currents up to 1A.
A internal reset cuicuit generates a reset pulse when the output 1 decrease below the regulated voltage value.
Output 2 can be disabled by TTL input.
Shot circuit and themal protections are included.
(2) Feature
• output currents up to 1A
• fixed precision Output 1 voltage 5.1V 2%
• fixed precision Output 2 voltage 12V 2%
• output 1 with Reset facility
• output 2 with Disable by TTL input
• short circuit protection at both outputs
• thermal protection
• low drop output voltage
