ELECTRICAL CHARACTERISTICS

(1) (2)

Limits in standard typeface are for TA = 25°C. Limits in boldface type apply over the full operating junction temperature range

(–40°C

≤ TJ ≤ +125°C). Unless otherwise noted, specifications apply to the LP5904 Typical Application Circuit with: VIN = VOUT

(NOM) + 1.0V, VEN = 1.2V, CIN = 1.0 µF, COUT = 1.0 µF, IOUT = 1.0 mA.

(1)

All voltages are with respect to the potential at the GND pin.

(2)

Min and Max limits are specified by design, test, or statistical analysis. Typical numbers are not specified, but do represent the most

likely norm.

(3)

The device maintains a stable, regulated output voltage without a load current.

(4)

Quiescent current is defined here as the difference in current between the input voltage source and the load at VOUT.

(5)

Ground current is defined here as the total current flowing to ground as a result of all input voltages applied to the device.

(6)

Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100 mV below its

nominal value. This specification does not apply for input voltages below 2.2V.

(7)

Short Circuit Current is measured with VOUT pulled to 0V and VIN worst case = 5.5V.

(8)

This specification is ensured by design.

(9)

There is a 1M

Ω resistor between VEN and ground on the device.
