SLVS719E – JUNE 2008 – REVISED AUGUST 2009 1.5-A LOW-NOISE FAST-TRANSIENT-RESPONSE LOW-DROPOUT REGULATOR 1 FEATURES 2 • Optimized for Fast Transient Response • Output Current: 1.5 A • Dropout Voltage: 340 mV • Low Noise: 40 μVRMS (10 Hz to 100 kHz) • 1-mA Quiescent Current • No Protection Diodes Needed • Controlled Quiescent Current in Dropout • Fixed Output Voltages: 1.5 V, 1.8 V, 2.5 V, and 3.3 V • Adjustable Output Voltage: 1.21 V to 20 V • Less Than 1- μA Quiescent Current in Shutdown • Stable with 10- μF Output Capacitor • Stable with Ceramic Capacitors • Reverse-Battery Protection • No Reverse Current • Thermal Limiting APPLICATIONS • 3.3-V to 2.5-V Logic Power Supplies • Post Regulator for Switching Supplies DESCRIPTION/ORDERING INFORMATION The TL1963A-xx is a low-dropout (LDO) regulator optimized for fast transient response. The device can supply 1.5 A of output current with a dropout voltage of 340 mV. Operating quiescent current is 1 mA, dropping to less than 1 μA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the TL1963A-xx regulators have very low output noise, which makes them ideal for sensitive RF supply applications. Output voltage range is from 1.21 V to 20 V. The TL1963A-xx regulators are stable with output capacitors 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 devices are available in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, and 3.3 V, and as an adjustable device with a 1.21-V reference voltage. The TL1963A-xx regulators are available in the 5-pin TO-263 (KTT), 6-pin TO-223 (DCQ), and 3-pin SOT-223 (DCY) packages. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD, PowerFLEX are trademarks of Texas Instruments.
