Microminiature Low-Noise, Low-Saturation Three-Pin Regulator MM1320
Microminiature Low-Noise, Low-Saturation Three-Pin Regulator
Monolithic IC MM1320
Outline
This IC is a microminiature low-noise stabilized power supply device featuring a highly precise output voltage
and a small input/output voltage difference of only 0.15V at an output current of 60mA.
The IC delivers output currents of up to 200mA, and through use of a noise pin output noise is diminished
even further. An on/off pin can be used to turn the output on and off.
Features
1. Input/output voltage difference 0.15V typ. (IO=60mA)
2. Output noise voltage 30µV
RMS typ. (Cn=0.01µF)
3. Maximum output current 150mA max.
4. No-load input current 170µA typ.
5.
With internal overcurrent protection and thermal shutdown circuits
6. Output voltage ranks 2~3.3V (0.1 V steps)
3.5V, 4V, 4.5V, 5V
7. Output on/off control function High : ON, Low : OFF
