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., IO=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.

· Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The ESR of capacitor must be defined in ESR stability area.
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.
5. The capacitor is connected to Cn must have low leakage current characteristics,
because Cn pin is high impedance.
6. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic
diode from output to input. In such application, the external bypass diode must be connected
between output and input pin.
