Ultralow Quiescent Current: 3µA
cent current is 3µA. Ground pin current remains at less n
Input Voltage Range: 2.0V to 45V
than 5% of output current as load increases. In shutdown, n
Output Current: 20mA
quiescent current is less than 1µA. n
Dropout Voltage: 300mV
The LT3007 regulators optimize stability and transient n
Adjustable Output (VADJ = VOUT(MIN) = 600mV)
response with low ESR ceramic capacitors, requiring a n
Fixed Output Voltages: 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V
minimum of only 2.2µF. The regulators do not require n Output Tolerance: ±2% Over Load, Line and the addition of ESR as is common with other regulators. Temperature Internal protection circuitry includes current limiting, n Stable with Low ESR, Ceramic Output Capacitors thermal limiting, reverse-battery protection and reverse- (2.2µF Minimum) current protection. n Shutdown Current: <1µA n Current Limit Protection The LT3007 series are ideal for applications that require n Reverse-Battery Protection moderate output drive capability coupled with ultralow n Thermal Limit Protection standby power consumption. The device is available in n TSOT-23 Package fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V, and an adjustable version with an output voltage range
APPLICATIONS
of 0.6V to 44.5V. The LT3007 is available in the thermally enhanced 8-lead TSOT-23 package. n Automotive L, LT, LTC, LTM, Linear Technology and the Linear logo are registered and ThinSOT is a n Low Current Battery-Powered Systems trademark of Linear Technology Corporation.
