These devices, which operate over an input range of 2.5V to 10V, are stable with any capacitor ≥ 0.47µF. The 2.5V to 10V input voltage range, combined with 3.2µA quiescent current, makes this device particularly well-suited for two-cell alkaline, and two-cell lithium, and other low quiescent current sensitive battery applications. The low dropout voltage and low quiescent current allow operation at extremely low power levels. Therefore, the devices are ideal for power battery management ICs. Specifically, because the device is enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously-operating, battery-charging ICs. The typical PNP pass transistor has been replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the low dropout voltage (typically 415mV at 50mA of load current) is directly proportional to the load current. The quiescent current (3.2µA, typical) is stable over the entire range of the output load current (0mA to 80mA).

SBVS116 – DECEMBER 2008 APPLICATION INFORMATION The TPS714xx family of LDO regulators has been optimized for ultralow power applications such as the MSP430 microcontroller. Its ultralow supply current maximizes efficiency at light loads, and its high input voltage range makes it suitable for supplies such as unconditioned solar panels. TPS71433 VIN IN C1 0.1mF OUT GND VOUT 0.47mF Figure 15. Typical Application Circuit (Fixed Voltage Version) External Capacitor Requirements Although not required, a 0.047µF or larger input bypass capacitor, connected between IN and GND and located close to the device, is recommended to improve transient response and noise rejection of the power supply as a whole. A higher-value input capacitor may be necessary if large, fast-rise-time load transients are anticipated and if the device is located several inches from the power source. The TPS714xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. Any capacitor (including ceramic and tantalum) that is greater than or equal to 0.47µF properly stabilizes this loop. Power Dissipation and Junction Temperature To ensure reliable operation, worst-case junction temperature should not exceed +125°C. This restriction limits the power dissipation that the regulator can manage in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(MAX), and the actual dissipation, PD, which must be less than or equal to PD(max). The maximum-power-dissipation limit is determined using Equation 1: T max * T A P D(max) + J R qJA (1) Where: • • • TJmax is the maximum allowable junction temperature. RθJA is the thermal resistance junction-to-ambient for the package (see the Power Dissipation Rating table). TA is the ambient temperature. The regulator dissipation is calculated using Equation 2: P D + ǒVIN * VOUTǓ I OUT (2) Power dissipation resulting from quiescent current is negligible. Regulator Protection The TPS714xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input voltage drops below the output voltage (for example, during power-down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be appropriate. The TPS714xx features internal current limiting. During normal operation, the TPS714xx limits output current to approximately 500mA. When current limiting engages, the output voltage scales back linearly until the over-current condition ends. There is no internal thermal shutdown circuit in this device; therefore, care must be taken not to exceed the power dissipation ratings of the package during a fault condition. This device does not have undervoltage lockout; therefore, this constraint should be taken into consideration for specific applications.

The output voltage is calculated using Equation 3: V OUT + VREF ǒ1 ) R1 Ǔ R2 (3) where: VREF = 1.205V typ (the internal reference voltage) Resistors R1 and R2 should be chosen for approximately a 1.5µA divider current. Lower value resistors can be used for improved noise performance, but the solution consumes more power. Higher resistor values should be avoided because leakage current out of the FB pin across R1/R2 creates an offset voltage that artificially increases the feedback voltage and thus erroneously decreases VOUT. The recommended design procedure is to choose R2 = 1MΩ to set the divider current at 1.5µA, and then calculate R1 using Equation 4: V OUT R1 + *1 R2 V REF ǒ Ǔ (4) TPS71401 VIN OUTPUT VOLTAGE PROGRAMMING GUIDE IN 0.1mF OUTPUT VOLTAGE R1 R2 1.8V 392MW 806kW 2.8V 1.07MW 806kW 5.0V 2.55MW 806kW VOUT OUT R1 0.47mF FB GND R2 Figure 16.
