LTC6652
t ypical perForMance characteristics Characteristic curves are similar for most LTC6652s. Curves from the LTC6652-1.25, LTC6652-2.5 and the LTC6652-5 represent the extremes and typical of the voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output. Power Supply Rejection Ratio SHDN Input Voltage Thresholds vs Frequency Output Impedance vs Frequency vs VIN

pin Functions DNC (Pin 1):
Do Not Connect.
GND (Pin 4):
Device Ground.
VIN (Pin 2):
Power Supply. The minimum supply input is
VOUT (Pin 6):
Output Voltage. An output capacitor is not VOUT + 300mV or 2.7V; whichever is higher. The maximum required. For some applications, a capacitor between 0.1µF supply is 13.2V. Bypassing VIN with a 0.1µF capacitor to to 10µF can be beneficial. See the graphs in the Typical GND will improve PSRR. Performance Characteristics section for further details.
SHDN (Pin 3):
Shutdown Input. This active low input
GND (Pins 5,7,8):
Internal Function. Ground these pins. powers down the device to <2µA. For normal operation tie this pin to VIN. 6652fg For more information www.linear.com/LTC6652 9 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Available Options Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
