LT3007 Series

Low Dropout Fault Tolerant  
Linear Regulators  
DESCRIPTION  
The LT®3007 series are micropower, low dropout voltage  
(LDO) linear regulators. The devices supply 20mA output  
current with a dropout voltage of 300mV. No-load quies-  
cent current is 3µA. Ground pin current remains at less  
than 5% of output current as load increases. In shutdown,  
quiescent current is less than 1µA.  
FEATURES  
n
FMEA Fault Tolerant:  
Output Stays at or Below Regulation Voltage During  
Adjacent Pin Short or if a Pin Is Left Floating

Ultralow Quiescent Current: 3µA

Output Current: 20mA

Dropout Voltage: 300mV  
The LT3007 regulators optimize stability and transient  
response with low ESR ceramic capacitors, requiring a  
minimum of only 2.2µF. The regulators do not require  
the addition of ESR as is common with other regulators.  
Internal protection circuitry includes current limiting,  
thermal limiting, reverse-battery protection and reverse-  
current protection.

The LT3007 series are ideal for applications that require  
moderate output drive capability coupled with ultralow  
standby power consumption. The device is available in  
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  
of 0.6V to 44.5V. The LT3007 is available in the thermally  
enhanced 8-lead TSOT-23 package.
