Texas Instruments Voltage Regulators - Linear TPS79328YEQR

The TPS79328YEQR is a low-dropout (LDO) linear voltage regulator designed for low-power applications, capable of delivering up to 200 mA of output current. It features a high power-supply rejection ratio (PSRR) of 70 dB at 10 kHz, which is beneficial for noise-sensitive applications such as RF electronics. The device exhibits low output voltage noise of approximately 32 OºV RMS at a 2.8 V output with a 0.1 OºF bypass capacitor, making it suitable for portable devices like handsets and PDAs. This regulator has a fast start-up time of approximately 50 Oºs and operates with a typical quiescent current of 170 OºA, reducing to less than 1 OºA in standby mode. It is stable with a small 2.2 OºF ceramic capacitor on the output, ensuring excellent line and load transient response. The TPS79328YEQR is available in a compact 5-pin DSBGA package, which contributes to its suitability for space-constrained applications.
