Regulated 12V ±5% Output Voltage  
The LTC®1262 is a regulated 12V, 30mA output DC/DC  
converter. It is designed to provide the 12V ±5% output  
necessary to program byte-wide flash memories. The  
output will provide up to 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.  
No Inductors  
Supply Voltage Range: 4.75V to 5.5V  
Guaranteed 30mA Output  
Low Power: ICC = 500µA  
ICC in Shutdown: 0.5µA  
8-Pin PDIP or SO-8 Package  
O U  
The TTL compatible shutdown pin can be directly con-  
nected to a microprocessor and reduces the supply cur-  
rent to less than 0.5µA. The LTC1262 offers improved  
shutdown current performance and requires fewer exter-  
nal components than competing solutions.
