The TPS79933DDCR is a low-dropout (LDO) linear voltage regulator designed to provide a stable output current of up to 200 mA. It features a low quiescent current of 40 OºA, making it suitable for battery-powered applications. The device offers fixed output voltages ranging from 1.2 V to 4.5 V, as well as adjustable outputs from 1.20 V to 6.5 V. With a dropout voltage of only 100 mV at full load, it ensures efficient operation. The TPS79933DDCR boasts a high power supply rejection ratio (PSRR) of 66 dB at 1 kHz and 51 dB at 10 kHz, contributing to its low noise performance. It is stable with a low equivalent series resistance (ESR) output capacitance of 2 OºF, which enhances transient response for both load and line changes. The device includes inrush current protection when enabled, ensuring safe startup. Operating over a temperature range of -40¬8C to +125¬8C, the TPS79933DDCR is available in a compact SOT-23-THIN package, making it suitable for space-constrained applications such as smartphones, wearable electronics, and wireless communication devices.
