LTC1262CS8#PBF

LTC1262 is a regulated output DC/DC converter. It is designed to provide the 12V ±5% output necessary to program byte-wide flash memories. The output will provide upto 30mA from input voltages as low as 4.75V without using any inductors. Only four external capacitors are required to complete an extremely small surface mountable circuit. The TTL compatible shutdown pin can be directly connected to a microprocessor and reduces the supply current to less than 0.5µA. This device offers improved shutdown current performance and requires fewer external components than competing solutions. It is widely used in application such as 12V flash memory programming supplies, compact 12V op-amp supplies, battery-powered systems etc.
