MITSUMI
Low-Saturation voltage 1.5A LDO MM185x Series
Low-Saturation voltage 1.5A LDO
Monolithic IC MM185x Series
Outline
This IC is a 1.5A LDO with a low saturation voltage.
In addition to a low-saturation voltage (0.26V typ., I
O
=1.5 A), the device has a low voltage output with a
minimum of 0.9 V, and is therefore capable of low-voltage operation.
This device is offered in the PKG TO-252-5 package featuring high heat dissipation and the small-sized PKG
HSOP-8 package.
For protection, it includes an over-current protection circuit and a thermal shutdown circuit.
Features
1. Supply Current 1mA typ. (No-Load)
2. Supply Current 1µA max. (OFF)
3. Output Voltage Range 0.9V~5.0V
4. Output Voltage accuracy ±2%
5. Dropout Voltage 0.26V typ. (I
O
=1.5A)
6. Line Regulation 10mV typ. (V
O

7. Load Regulation 19mV typ. (I
O
=0~1.5A)
8. Ripple rejection 65dB typ. (f=1kHz)
9. Thermal shutdown
10. Input & Output Capacitor 1µF
