Power is supplied to the devices through the IN pin. The IN pin should be locally bypassed to ground if the UM365XXS series are more than a few inches away from another source of bulk capacitance. In general, the output impedance of a battery rises with frequency, so it is usually advisable to include an input bypass capacitor in battery-powered circuits. A capacitor in the range of 0.1μF to 1μF is usually sufficient. The UM365XXS series are designed to withstand reverse voltages on the IN pin with respect to both ground and the output pin. In the case of a reversed input, which can happen if a battery is plugged in backwards, the UM365XXS will act as if there is a large resistor in series with its input with only a small amount of current flow. OUT (Pin 2): Voltage Regulated Output. The OUT pin supplies power to the load. A minimum output capacitor of 1μF is required to ensure stability. Larger output capacitors may be required for applications with large transient loads to limit peak voltage transients. See the Applications Information section for more information on output capacitance. GND (Pin3): Ground and Heat Sink. Solder to a ground plane or large pad to maximize heat dissipation. Typical Application Circuit OUT 1μF 1μF VOUT VIN IN GND VIN=4.3V to 5.3V(1V/div) VOUT=3.3V (100mV/div) VIN=5.3V to 4.3V(1V/div) VOUT=3.3V (100mV/div) VIN=4.3V,Iout=10mA , 100us/div VIN=4.3V,Iout=10mA , 100us/div |
