6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)⁽¹⁾⁽²⁾

	MIN	MAX	UNIT
V_(MAX) All pins (with respect to GND)	–0.3	12	V
I_OUT⁽⁴⁾	Internally limited		V
Power dissipation⁽³⁾	Internally limited		V
Junction temperature	–40	150	°C
Storage temperature, T_stg	−65	150	°C

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

(3) At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink values (if a heatsink is used). When using the WSON package, refer to Leadless Leadframe Package (LLP) (SNOA401) and the WSON Mounting section in this data sheet. If power dissipation causes the junction temperature to exceed specified limits, the device will go into thermal shutdown.

(4) If used in a dual-supply system where the regulator load is returned to a negative supply, the OUT pin must be diode clamped to ground.

6.2 ESD Ratings: LP38691-ADJ, LP38693-ADJ

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2000	V

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

6.3 ESD Ratings: LP38691-ADJ-Q1, LP38693-ADJ-Q1

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per AEC Q100-002⁽¹⁾	2000	V

(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.

(3) The PCB for the WSON (NGN) package R_θJA includes thermal vias under the exposed thermal pad per EIA/JEDEC JESD51-5.

(1) Typical numbers represent the most likely parametric norm for 25°C operation.

(2) Output voltage line regulation is defined as the change in output voltage from nominal value resulting from a change in input voltage.

(3) Output voltage load regulation is defined as the change in output voltage from nominal value as the load current increases from 1 mA to full load.
