Specification Descriptions and

Test Circuits

1.1.1

OUTPUT VOLTAGE

Output voltage is the reference voltage that is available

on the output pin (VOUT).

1.1.2

INPUT VOLTAGE

The input (operating) voltage is the range of voltage

that can be applied to the VIN pin and still have the

device produce the designated output voltage on the

VOUT pin.

1.1.3

OUTPUT VOLTAGE DRIFT (TCVOUT)

The output temperature coefficient or voltage drift is a

measure of how much the output voltage (VOUT) will

vary from its initial value with changes in ambient

temperature. The value specified in the electrical

specifications is measured and equal to:

EQUATION 1-1:

Electrical Characteristics: Unless otherwise indicated, TA =+25°C, VIN = 5.0V, VSS =GND, IOUT = 0 mA and CL =1 µF.

Note

The input capacitor is optional; Microchip recommends using a ceramic capacitor.

These parts are tested at both 1 µF and 10 µF to ensure proper operation over this range of load capacitors. A wider

range of load capacitor values has been characterized successfully, but is not tested in production.

Electrical Characteristics: Unless otherwise indicated, TA =+25°C, VIN = 5.0V and VSS =GND.
