6 Specifications

6.1 Absolute Maximum Ratings

Over operating temperature range (unless otherwise noted).⁽¹⁾⁽²⁾

		MIN	MAX	UNIT
Voltage	V_IN	–0.3	24	V
Voltage	V_OUT	–0.3	16.5	V
	Peak output current	Internally limited
Temperature	Junction, T_J	–40	150	°C
Temperature	Storage, 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) All voltage values are with respect to network ground terminal.

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.

		MIN	NOM	MAX	UNIT
V_IN	Input supply voltage	2.5		24	V
I_OUT	Output current	0		50	mA
C_IN	Input capacitor	0	0.047		µF

6.5 Electrical Characteristics

Over operating junction temperature range (T_J = –40°C to 125°C), V_IN = V_OUT(nom) + 1 V, I_OUT = 1 mA, and C_OUT = 1 μF, unless otherwise noted. Typical values are at T_J = 25°C.

V_IN	Input voltage⁽¹⁾		I_O = 50 mA	3		24	V

V_OUT	Accuracy⁽¹⁾	Over V_IN, I_OUT, and T	V_OUT + 1 V ≤ V_IN ≤ 24 V	–4%		4%
V_OUT	Accuracy⁽¹⁾	Over V_IN, I_OUT, and T	100 μA ≤ I_OUT ≤ 50 mA	–4%		4%
I_GND	Ground pin current⁽²⁾		0 ≤ I_OUT ≤ 50 mA, T_J = –40°C to 85°C		3.2	4.2	μA

ΔV_OUT_(ΔIOUT)	Load regulation		I_OUT = 100 μA to 50 mA		22		mV
ΔV_OUT_(ΔVIN)	Output voltage line regulation ⁽¹⁾		V_OUT + 1 V < V_IN ≤ 24 V		20	60	mV
V_n	Output noise voltage		BW = 200 Hz to 100 kHz, C_OUT = 10 μF, I_OUT = 50 mA		575		μVrms
I_CL	Output current limit		V_OUT = 0 V, V_IN≥ 3.5 V	125		750	mA
I_CL	Output current limit		V_OUT = 0 V, V_IN< 3.5 V	90		750	mA
PSRR	Power-supply ripple rejection		f = 100 kHz, C_OUT = 10 μF		60		dB
V_DO	Dropout voltage V_IN = V_OUT(nom) – 0.1 V		I_OUT = 50 mA		415	750	mV

(1) Minimum V_IN = V_OUT + V_DO or the value shown for Input voltage in this table, whichever is greater.

(2) See Figure 10. The TPS715 family employs a leakage null control circuit. This circuit is active only if output current is less than pass FET leakage current. The circuit is typically active when output load is less than 5 μA, V_IN is greater than 18 V, and die temperature is greater than 100°C.
