Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and conditions,

see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Office/ Distributors for availability and

specifications.

(3)

The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin.

(4)

Operating junction temperature must be evaluated, and derated as needed, based on ambient temperature (TA), power dissipation (PD),

maximum allowable operating junction temperature (TJ(MAX)), and package thermal resistance (θJA). See Application Information.

Electrical Characteristics

LP38500/2–ADJ

Unless otherwise specified: VIN = 3.3V, IOUT = 10 mA, CIN = 10 µF, COUT = 10 µF, VEN = VIN, VOUT = 1.8V. Limits in standard

type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C.

Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent the most

likely parametric norm at TJ = 25°C, and are provided for reference purposes only.

(1)

The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included

in the adjust voltage tolerance specification.

(2)

Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. For

any output voltage less than 2.5V, the minimum VIN operating voltage is the limiting factor.

(3)

Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the voltage at the

input.

(4)

Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in the load current.
