Working PrincipleThe ADP170AUJZ-1.25-R7 operates using a two-stage linear regulator that consists of a PFM/PWM controller followed by a compensation stage. The PFM/PWM controller regulates the input voltage and provides the variable pulse width control signal based on the output current requirement. The compensation section consists of proportional-integral control loop, error amplifier, and voltage reference. The error amplifier is used to compare the output voltage to the reference voltage. The amplitude and width of the P of the PWM are adjusted based on the output voltage and required current respectively. The error amplifier\'s output is also fed back to the pass transistor to ensure the output voltage is maintained in the specified range. The device uses a lowdropout linear regulator that offers a high efficiency when compared to other linear regulator solutions. The low dropout regulator topology ensures the device can operate with low quiescent current and provides excellent output regulation. As the device does not dissipate much power, it can be operated without a heatsink. ConclusionThe ADP170AUJZ-1.25-R7 from Texas Instruments is a low-power linear voltage regulator with excellent load regulation and low quiescent current. It can be used in a variety of applications that require reliable and accurate regulation of input voltages. Its low-power design means it is particularly suitable for portable battery-powered applications such as mobile phones, base stations, tablets, and automotive electronics.
