MITSUMI
150mA Regulator
Monolithic IC MM157
150mA Regulator MM157 N, 161 N
N, 161 N
Outline
This IC is an ultra-small, low noise, stable power supply that supports ceramic capacitors (low ESR) Output
current goes up to 150mA, and use of a noise pin reduces output noise even further.
Output ON/OFF can be controlled with the ON/OFF pin.
Features
1. I/O voltage difference
0.10V typ. (IO=50mA)
2. Output noise voltage
30µVrms typ. (Cn=0.01µF)
3. Recommended maximum output current 150mA max.
4. No-load current consumption
85µA typ.
5. Built-in overcurrent protection and thermal shutdown circuits
6. Output voltage rank
1.8 ~ 5.0V (0.1V steps)
7. Output ON/OFF control function
High: ON, Low: OFF
Package
SOT-25A (MM157 N, MM161 N)
* contains the output voltage rank.
Applications
1. Cordless telephone
2. Cellular telephone, PHS
3. Portable MD
4. Other battery-powered portable equipment

Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. Use a capacitance that is within the ESR characteristics stable range for output capacity.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 1µF and B type temperature characteristics.
3. The wire of Vcc and GND is required to print full ground plane for noise and stability.
4. The input capacitor must be connected a distance of less than 1cm from input pin.
