Description
1
I
Input; Battery Supply Input Voltage.
2
INH
Inhibit; Set low
to inhibit.
3
GND
Ground; Pin 3 internally connected to heatsink.
4
NC / VA
Not connected for fixed voltage version / Voltage Adjust Input for adjustable voltage version; use an external
voltage divider to set the output voltage
5
Q
Use 22 F, ESR < 2.5 at 10 kHz to ground with the 5.0 V and adjustable regulators. See Figures 3, 4, and 5.
Use 10 F, ESR < 1.8 at 10 kHz to ground with the 3.3 V, 2.5 V, and 1.8 V regulators. See Figures 3 and 6.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
*During the voltage range which exceeds the maximum tested voltage of I, operation is assured, but not specified. Wider limits may apply. Thermal
dissipation must be observed closely.
