... GND (Pin 2): Ground and Heat Sink. Solder to a ground plane or large pad to maximize heat dissipation. SHDN (Pin 3, Fixed and SD Devices): Shutdown, Active Low. This pin is used to put the LTC1844 into shutdown. The SHDN pin current is typically less than 10nA. The SHDN pin cannot be left floating and must be tied to the input pin if not used ...

... TIME ( s) Figure 1. LTC1844-2.5 Transient Response 1mA to 50mA to 1mA Adjustable Operation The adjustable version of the LTC1844 has an output voltage range of 1.25V to 6V. The output voltage is set by the ratio of two external resistors as shown in Figure 2. The device servos the output to maintain the ADJ pin voltage ...

... OUT IN The LTC1844 series regulators have internal thermal lim- iting designed to protect the device during momentary overload conditions. For continuous normal conditions, the maximum junction temperature rating of 125 C must not be exceeded important to give careful consider- ...

... Current flow into the device will be limited to less than 500 A (typically less than 200 A) and only a small negative voltage will appear at the output (~ –300mV with no load). The LTC1844 will protect both itself and the load against batteries plugged in backward. In circuits where a backup battery is required, several different input/output conditions can occur ...
