CM2836/B/C
300mA LOW ESR CMOS LDO WITH ENABLE
GENERAL DESCRIPTION
The CM2836/B/C family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30μA typ.), low dropout voltage, and high output voltage accuracy, making them ideal for battery applications. EN input connected to CMOS has low bias current. The space-saving SC70 package is attractive for “Pocket” and “Hand Held” applications. These rugged devices have both Thermal Shutdown, and Current limit to prevent device failure under the “Worst” of operating conditions. In application requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground. The CM2836/B/C is stable with a Low ESR output capacitance of 1.0μF or greater.
FEATURES
Very Low Dropout Voltage Low Current Consumption: Typ. 30μA, Max. 35μA More Options Output Voltage High Accuracy Output Voltage: +/- 2% Guaranteed 300mA Output Input Range up to 7.0V Thermal Shutdown Current Limiting Stability with Low ESR Capacitors Compact Package: SOT-23-3 / SOT-23-5 / SOT-89 / SC70-5 Factory Pre-set Output Voltages Low Temperature Coefficient
APPLICATIONS
Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals
