[quote user="Manzar Laghari"]i have used voltage divider circuit to down the voltage from 5V to 3.6V and supplying to IC at Vcc pin and GND[/quote] And there is your issue located. You cannot use a voltage divider to power your circuit. The voltage drop is current dependant. The more current your circuit needs, the less voltage it will see. Use a 3.3V low dropout regulator or a combination of a resistor and a Zener diode to bring the 5V down. Dennis
