The S-1137A27-U5T1G is a three-terminal positive voltage regulator which is designed to provide a regulated output voltage. It contains an on-chip voltage reference, an error amplifier, a current limiter and a series pass transistor. The output voltage can be set between 2.85V and 10V by adjusting the external feedback divider network. It does not require a large heat sink, delivers high efficiency and is available in an SO-8 package.
The working principle of the S-1137A27-U5T1G is based on the output of the series pass transistor. A voltage reference circuit provides a fixed voltage to the non-inverting input of the error amplifier. The voltage at the PW pin (voltage divider) is compared to the voltage reference. The error amplifier adjusts the output voltage according to the difference in the inputs. The output of the error amplifier is connected to the base of the series pass transistor, thus controlling the output voltage of the regulator. The current limitation is implemented using the current-sense resistor, RS.
