Regulator+Reset IC
Monolithic IC MM1437
Outline
This IC combines a low saturation 5V regulator, adapted for low power consumption, and a reset function
(regulator output monitoring), for which there is significant market need, that uses the built-in 4.2V detection
delay circuit.
Features
1. Small input/output voltage difference
2. High input voltage
0.25V typ.
18V max.
3. Internal thermal shutdown circuit.
4. Internal current-limiting circuit.
5. Adjustment-free reset detection voltage
4.2V typ.
6. Easy to set delay time from voltage detection to reset release.
Package
SOP-7
SIP-5
Applications
TV, monitors, air conditioners, others.

Measuring Circuit
Application Circuit
Note 1 : This regulator is not internally compensated and thus requires an external output-capacitor (COUT) for
stability.
-
Note 2 : RESET-terminal with a built-in pull-up resistance (10kΩ).
