com ULTRALOW-NOISE, HIGH-PSRR, FAST, RF, 500-mA LOW-DROPOUT LINEAR REGULATORS Check for Samples: TPS79501-Q1 SLVSAJ9 – SEPTEMBER 2010 FEATURES 1 •2 Qualified for Automotive Applications • 500-mA Low-Dropout Regulator With Enable • High PSRR (50 dB at 10 kHz) • Ultralow Noise (33 mVRMS, TPS79501-Q1) • Fast Start-Up Time (50 ms) • Stable With a 1-mF Ceramic Capacitor • Excellent Load/Line Transient Response • Low Dropout Voltage (110 mV at Full Load, TPS79501-Q1) APPLICATIONS • RF: VCOs, Receivers, ADCs • Audio • Bluetooth®, Wireless LAN DESCRIPTION The TPS79501-Q1 low-dropout (LDO), low-power linear voltage regulator features high power-supply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in a small outline SON package.
The device is stable with a small 1-mF ceramic capacitor on the output.
The TPS79501-Q1 uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 110 mV at 500 mA).
The device achieves fast start-up times (approximately 50 ms with a 0.
001-mF bypass capacitor) while consuming very low quiescent current (265 mA, typical).
Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 mA.
The TPS79501-Q1 exhibits approximately 33 mVRMS of output voltage noise at 3-V output with a 0.
1-mF bypass capacitor.
Applications with analog components that are noise-sensitive, such as portable RF electronics, benefit from the high-PSRR and low-noise features, as well as from the fast response time.
