LT1964

200mA, Low Noise,

Low Dropout Negative

Micropower Regulator

FEATURES

DESCRIPTION

TheLT^®1964isamicropowerlownoise,lowdropoutnega-

tive 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-pow-

ered applications. Quiescent current is well controlled in

dropout.

Low Noise: 30μV

(10Hz to 100kHz)

RMS

Low Quiescent Current: 30μA

Low Dropout Voltage: 340mV

Output Current: 200mA

Fixed Output Voltage: –5V

Adjustable Output from –1.22V to –20V

Positive or Negative Shutdown Logic

3μA Quiescent Current in Shutdown

Stable with 1μF Output Capacitor

Stable with Aluminum, Tantalum, or Ceramic

Capacitors

Thermal Limiting

Low Proﬁle (1mm) ThinSOT™ and (0.75mm) 8-Pin

3mm × 3mm DFN Packages

Other features of the LT1964 include low output noise.

With the addition of an external 0.01μF bypass capacitor,

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 volt-

age. The LT1964 regulators are available in a low proﬁle

(1mm) ThinSOT and the low proﬁle (0.75mm) 8-pin

(3mm × 3mm) DFN packages.
