7 Specifications

7.1 Absolute Maximum Ratings

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

	MIN	MAX	UNIT
Voltage at VIN, PG, VOS⁽²⁾	–0.3	7	V
Voltage at SW⁽²⁾⁽³⁾	–1	7	V
Voltage at FB⁽²⁾	–0.3	3.6	V
Voltage at EN, MODE⁽²⁾	–0.3	VIN + 0.3	V
Sink current at PG	0	0.5	mA
Operating junction temperature, T_J	–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 and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.

(2) All voltage values are with respect to network ground terminal.

(3) During operation, device switching.

7.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2000	V
V_(ESD)	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±500	V

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

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions⁽¹⁾

V_OUT	Output voltage	0.5	4	V
I_SNOOZE	Load current in Snooze Mode		2	mA
T_J	Operating junction temperature	–40	125	°C

(1) Refer to the Application and Implementation section for further information.
