TPS7A6201-Q1 www.ti.com SLVSAA0B – NOVEMBER 2010 – REVISED MARCH 2012 DETAILED DESCRIPTION TPS7A6201 is a monolithic low dropout linear voltage regulator with programmable output voltage and an integrated fault protection. This voltage regulator is designed for low power consumption and quiescent current less than 25µA in light load applications.

TPS7A6201-Q1 SLVSAA0B – NOVEMBER 2010 – REVISED MARCH 2012 www.ti.com Charge Pump State Low Voltage Tracking At low input voltages the regulator drops out of regulation, the output voltage tracks input minus a voltage based on the load current (IOUT) and switch resistance (RSW) as shown in Figure DDD. This allows for a smaller input capacitor and can possibly eliminate the need of using a boost convertor during cold crank conditions. ON Hysteresis OFF 7.8 7.9 VIN (V) Figure 19.

TPS7A6201-Q1 SLVSAA0B – NOVEMBER 2010 – REVISED MARCH 2012 www.ti.com APPLICATION INFORMATION Typical application circuit for TPS7A6201 is shown in Figure 23. Depending upon an end application, different values of external components may be used. In order to program the output voltage, feedback resistors (R1 and R2) should be carefully selected. Using small resistors will result in higher current consumption, where as, using very large resistors will impact the sensitivity of the regulator.

TPS7A6201-Q1 www.ti.com SLVSAA0B – NOVEMBER 2010 – REVISED MARCH 2012 For optimum thermal performance, it is recommended to use a high K PCB with thermal vias between ground plane and solder pad/ thermal land pad. This is shown in Figure 25 (a) and (b). Further, heat spreading capabilities of a PCB can be considerably improved by using a thicker ground plane and a thermal land pad with a larger surface area.
