Low-Saturation Three-Pin Regulators with Externally Mounted Power Transistor MM1215 and 1216
Low-Saturation Three-Pin Regulators with Externally Mounted Power Transistor
Monolithic ICs MM1215 and 1216
Outline
These ICs are high-precision, high-voltage stabilized power supply devices which, by employing an externally
mounted power transistor are able to drive loads at large currents. The input/output voltage difference is a low
0.2V, and an internal protection circuit ensures that the devices can be used in a wide range of portable
equipment. Output on/off control is also provided.
Features
1. Input voltage 16V max.
2. Input/output voltage difference 0.2V typ.
3. Maximum driving current 15mA max.
4. No-load input current 250µA typ.
5. Thermal shutdown circuit provided
6. Output ranks E : 9.0V±2% I : 4.0±2%
F : 6.0V±2% J : 3.0±2%
G : 5.0V±2% Z : 3.3±2%
H : 4.5V±2%
