6.1 Absolute Maximum Ratings

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

		MIN	MAX	UNIT
Voltage	V_IN	–0.3	+6.0	V
	V_EN and V_VSET	–0.3	V_IN + 0.3⁽²⁾
	V_OUT	–0.3	V_IN + 0.3
Current	I_OUT	Internally limited

Total continuous power dissipation, P_DISS		See Thermal Information
Temperature	Operating junction, T_J	–40	125	°C
Temperature	Storage, T_stg	–55	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) V_EN and V_VSET absolute maximum rating are V_IN + 0.3V or +6.0V, whichever is less.

6.2 ESD Ratings

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

(1) The output voltage for V_SET = low/high is programmed at the factory.

(2) No V_SET pin on the adjustable version.

(3) No dynamic voltage scaling on the adjustable version.

(4) V_DO is not measured for devices with V_OUT(nom) < 2.3 V because minimum V_IN = 2.2 V.

(5) I_GND = 800 nA (max) up to 100°C.

(6) Time from V_EN = 1.2 V to V_OUT = 90% (V_OUT(nom)).

(7) Time from V_EN = 0.4 V to V_OUT = 10% (V_OUT(nom)).

(8) See Shutdown for more details.

(9) Adjustable version only.

(10) The TPS78001 FB pin is tied to V_OUT. Adjustable version only.
