TPS71319 TPS71334 www.ti.com SBVS055A – DECEMBER 2004 – REVISED JANUARY 2005 APPLICATION INFORMATION The TPS713xx family of dual low-dropout (LDO) regulators has been optimized for use in noise-sensitive battery-operated equipment. The device features extremely low dropout, high PSRR, ultralow output noise, and low quiescent current (190 µA typically per channel). When both outputs are disabled, the supply currents are reduced to less than 2µA.

TPS71319 TPS71334 www.ti.com SBVS055A – DECEMBER 2004 – REVISED JANUARY 2005 PROGRAMMING THE TPS71202 ADJUSTABLE LDO REGULATOR C1 The output voltage of the TPS71202 dual adjustable regulator is programmed using an external resistor divider, as shown in Figure 24. The output voltage is calculated using Equation 1: V OUT VREF 1 R1 R2 (1) where VREF = 1.225 V (the internal reference voltage). Resistors R2 and R4 should be chosen for approximately a 40 µA divider current.

TPS71319 TPS71334 www.ti.com SBVS055A – DECEMBER 2004 – REVISED JANUARY 2005 SUPERVISOR DESCRIPTION The TPS713xx has an on-chip supply voltage supervisor (SVS) that monitors the voltage at OUT2. The RESET output will assert if VOUT2 is below the reset threshold (VIT). When OUT2 exceeds the reset threshold plus hysteresis (VHYS), the RESET output will remain low for the specified delay time (tD).
PAGE 12
TPS71319 TPS71334 www.ti.com SBVS055A – DECEMBER 2004 – REVISED JANUARY 2005 TRANSIENT RESPONSE As with any regulator, increasing the size of the output capacitor will reduce over/undershoot magnitude but increase duration of the transient response. In the adjustable version, the addition of a capacitor, CFB, from the output to the feedback pin will also improve stability and transient response.
