(1) These units are intended for engineering evaluation only. They are processed to a non-compliant flow (for example, no burn-in, and so forth) and are tested to a temperature rating of 25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Parts are not specified for performance over the full MIL specified temperature range of –55°C to 125°C or operating life.

3 Description

The TPS7A4501-SP is a low-dropout (LDO) regulator optimized for fast-transient response. The 5962-1222402VHA can supply 750 mA of output current with a dropout voltage of 300 mV. The 5962R1222403VXC can supply 1.5 A of output current with a dropout voltage of 320 mV. Quiescent current is well controlled; it does not rise in dropout, as with many other regulators. In addition to fast transient response, the TPS7A4501-SP regulator has very-low output noise, which makes it ideal for sensitive RF supply applications.

5 Description (continued)

Output voltage range is from 1.21 to 20 V. The TPS7A4501-SP is stable with output capacitance as low as 10 μF. Small ceramic capacitors can be used without the necessary addition of ESR, as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection. The device is available as an adjustable device with a 1.21-V reference voltage. The 5962-1222402VHA is available in 10-pin CFP (U) package and 5962R1222403VXC is available in thermally-enhanced 10-pin CFP (HKU) package. Known good die (KGD) option is available for both 5962-1222402V9A for non-RHA version and 5962R1222403V9A for RHA.

Pin Functions

PIN		I/O	DESCRIPTION
NAME	NO.	I/O	DESCRIPTION
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 V_IN. 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.
	7
	8
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.
