3.3V Voltage regulator (33v regulator)

How does AMS1117-ASEMI low-voltage differential linear Regulator work?

1, AMS1117 is a low voltage difference linear regulator. Linear voltage regulator is the traditional voltage regulator power supply. That is, the input and output voltages are linearly adjustable regulators, different from switching regulators. Low voltage difference, pressure difference, input and output voltage difference. Conventional lineVoltage regulator power supply to make the output voltage stable.

2, the large pin on the AMS1117 is connected to the middle foot, which is the power output end. The on-chip trims of the AMS1117 adjust the reference voltage to within a 5% error, and the current limit is adjusted to minimize pressure caused by overloading the regulator and power circuit.

3, AMS1117 is a forward low voltage drop regulator, its voltage regulator is composed of a PNP driven NPN tube, the leakage voltage is defined as: VDROP=VBE VSAT.

Power supply. Ling-core micro LC1210-3V voltage regulator chip -- Shenzhen Hengli LC1210 is a 200mA, static power consumption is only 5uA, voltage up to 12V, low noise.

The functions of each pin of the power chip 1207 are as follows: VCC pin: This pin is the power supply pin of the chip and the input pin of the output overvoltage protection. RC foot: oblique wave compensation, Gree this air conditioning pin connected to the power supply, the function is not useful.

lc21206a citationThe pin function of the power chip has a unique AC voltage zero crossing signal detection and output control circuit.

The 8 pin description pins (COMP) of the power management chip are error amplifier compensation pins. The RC compensation network should be connected between the pin and the inverting input of the error amplifier (VFB) to improve the performance of the error amplifier. The foot (VFB) is the inverting input of the error amplifier.

1, is a 3V three-terminal voltage regulator chip, can only be replaced with the same model. This three-terminal voltage regulator chip input voltage is generally about 5V, output 3V, if the input voltage is normal, the output voltage is too low. There are only two scenarios. First, the output load has a short-circuit fault. Two, the chip has a problem.
