A: Input voltage VH is applied B: This IC starts operating, when VCC pin voltage rises VCC > VUVLO1 (Typ=13.5 V). Switching function starts when other protection functions are judged as normal. Then the VCC pin voltage drop because of consumption current of VCC pin. In the case of VCC < VCHG1 (Typ=8.7V), Apr 11, 2018 · 7805 is a three terminal linear voltage regulator IC with a fixed output voltage of 5V which is useful in a wide range of applications. Currently, the 7805 Voltage Regulator IC is manufactured by Texas Instruments, ON Semiconductor, STMicroelectronics, Diodes incorporated, Infineon Technologies, etc. Apr 04, 2019 · Input voltage (7V-35V) In this pin of the IC positive unregulated voltage is given in regulation. 2: GROUND: Ground (0V) In this pin where the ground is given. This pin is neutral for equally the input and output. 3: OUTPUT: Regulated output; 5V (4.8V-5.2V) The output of the regulated 5V volt is taken out at this pin of the IC regulator.
