6 Specifications
6.1 Absolute Maximum Ratings(1)
over operating ambient temperature range (unless otherwise noted)| MIN | MAX | UNIT | |
|---|---|---|---|
| Input voltage, VI (2) | –0.3 | 13.5 | V |
| Voltage at EN | –0.3 | VI + 0.3 | V |
| Maximum PG voltage | 16.5 | V | |
| Peak output current | Internally limited | ||
| Output voltage, VO (OUT, FB) | 7 | V | |
| Operating junction temperature, TJ | –40 | 150 | °C |
| Storage temperature, Tstg | –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 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 terminal ground.
6.2 ESD Ratings
| VALUE | UNIT | ||||
|---|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per AEC Q100-002(1) | ±2000 | V | |
| Charged-device model (CDM), per AEC Q100-011 | All pins | ±500 | |||
| Corner pins (1, 4, 5, and 8) | ±750 | ||||
(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
6.3 Recommended Operating Conditions
| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| VI | Input voltage(1) | 2.7 | 10 | V |
| VO | Voltage at OUT | 1.2 | 5.5 | V |
| IO | Output current(2) | 0 | 1 | A |
| TA | Operating ambient temperature(2) | –40 | 125 | °C |
(1) To calculate the minimum input voltage for the maximum output current, use the following equation: VI(min) = VO(max) + V(DO,max_load), where V(DO,max_load) is the dropout voltage at maximum load.
(2) Continuous current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time.
