LT1964IS5-SD#TRMPBF

LT®1964 is a micropower low noise, low dropout negative regulator. The device is capable of supplying 200mA of output current with a dropout voltage of 340mV. Low quiescent current (30μA operating and 3μA shutdown) makes the LT1964 an excellent choice for battery-powered applications. Quiescent current is well controlled in dropout. Other features of the LT1964 include low output noise. With the addition of an external 0.01μF bypass capacitor, output noise is reduced to 30μVRMS over a 10Hz to 100kHz bandwidth. The LT1964 is capable of operating with small capacitors and is stable with output capacitors as low as 1μF. Small ceramic capacitors can be used without the necessary addition of ESR as is common with other regulators. Internal protection circuitry includes reverse output protection, current limiting, and thermal limiting. The device is available with a fixed output voltage of –5V and as an adjustable device with a –1.22V reference voltage.

• Adjustable output voltage from -1.22V to -20V
• Positive or negative shutdown logic
• Stable with aluminum, tantalum, or ceramic capacitor
• 5-lead plastic SOT-23 package
• Temperature range from -40°C to 125°C
