Pin Functions

PIN I/O DESCRIPTION
NAME NO.
SHDN 1 I Shutdown. SHDN is used to put the TPS7A4501 regulator into a low-power shutdown state. The output is off when SHDN is pulled low. SHDN can be driven by 5-V logic, 3-V logic, or open-collector logic with a pullup resistor. The pullup resistor is required to supply the pullup current of the open-collector gate, normally several microamperes, and SHDN current, typically 3 μA. If unused, the user must connect SHDN to VIN. The device is in the low-power shutdown state if SHDN is not connected.
IN 2 I Input. Power is supplied to the device through IN. A bypass capacitor is required on this pin if the device is more than six inches away from the main input filter capacitor. In general, the output impedance of a battery rises with frequency, so it is advisable to include a bypass capacitor in battery-powered circuits. A bypass capacitor (ceramic) in the range of 1 to 10 μF is sufficient. The TPS7A4501 regulator is designed to withstand reverse voltages on IN with respect to ground and on OUT. In the case of a reverse input, which can happen if a battery is plugged in backwards, the device functions as if there is a diode in series with its input. No reverse current flows into the regulator, and no reverse voltage appears at the load. The device protects both itself and the load.

NC 5 NC This pin is not connected to any internal circuitry. It can be left floating or tied to VIN or GND.
OUT 6 O Output. The output supplies power to the load. To prevent oscillations, use a minimum output capacitor (ceramic) of 10 μF. Applications with large transient loads to limit peak voltage transients require larger output capacitors.

ADJ 9 I Adjust. This is the input to the error amplifier. ADJ is internally clamped to ±7 V. It has a bias current of 3 μA that flows into the pin. ADJ voltage is 1.21 V referenced to ground, and the output voltage range is 1.21 to 20 V.
GND 10 — Ground
Thermal Vias(1) — — The exposed thermal vias of the HKU package should be connected to a wide ground plane for effective heat dissipation. Refer to Figure 30 and Figure 31 for the typical footprint of the HKU package.
