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.
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.
