TPS796xx-Q1 www.ti.com SBVS154 – MARCH 2012 Ultralow-Noise, High-PSRR, Fast, RF, 1-A LOW-DROPOUT LINEAR REGULATORS Check for Samples: TPS796xx-Q1 FEATURES 1 23 Qualified for Automotive Applications AEC-Q100 Test Guidance With the Following Results: – Device Temperature Grade 1: –40°C to 125°C Ambient Operating Temperature Range – Device HBM ESD Classification Level H2 – Device CDM ESD Classification Level C3A 1-A Low-Dropout Regulator With Enable Available in Fixed and Adjustable (1.2 V to 5.5 V) Versions High PSRR (53 dB at 10 kHz) Ultralow-Noise (40 μVRMS, TPS79630-Q1) Fast Start-Up Time (50 μs) Stable With a 1-μF Ceramic Capacitor Excellent Load/Line Transient Response Very Low Dropout Voltage (250 mV at Full Load, TPS79630-Q1) SOT223-6 Package APPLICATIONS RF: VCOs, Receivers, ADCs Audio Bluetooth™, Wireless LAN DESCRIPTION The TPS796xx-Q1 family of low-dropout (LDO), lowpower, linear voltage regulators features high powersupply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in a small-outline SOT223-6 package. Each device in the family is stable with a small 1-μF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 250 mV at 1 A). Each device achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor) while consuming very low quiescent current (265 μA typical)....
