TPS7A4501 (ACTIVE)

Single Output LDO, 1.5A, Adj. (1.21V to 20V), Low Noise, Fast Transient Response

Description

The TPS7A45xx devices are low-dropout (LDO) regulators optimized for fast transient response. The device can supply 1.5 A of output current with a dropout voltage of 300 mV. Operating quiescent current is 1 mA, dropping to less than 1 µA in shutdown. Quiescent current is well controlled; it does not rise in dropout, as with many other regulators. In addition to fast transient response, the TPS7A45xx regulators have very low output noise, which makes them ideal for sensitive RF supply applications.

Output voltage range is from 1.21 V to 20 V. The TPS7A45xx regulators are 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 devices are available in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V, and as an adjustable device with a 1.21-V reference voltage. The TPS7A45xx regulators are available in the 5-pin TO-263 (KTT) and 6-pin TO-223 (DCQ) packages.
