Product details
Overview
ISL78301FVEBZ from Renesas Electronics (formerly Intersil) is a 5.0V fixed-output, automotive-grade linear regulator delivering 150mA with ultra-low 22–28µA quiescent current at no load and 295mV dropout at full load. It operates from 3V to 40V input-supporting cold-crank and load-dump conditions-and integrates EN control, thermal shutdown, and current limiting for always-on vehicle subsystems such as body control modules and infotainment power rails.
For engineers reviewing the ISL78301FVEBZ datasheet, ISL78301FVEBZ pinout, ISL78301FVEBZ application, or ISL78301FVEBZ equivalent, key selection criteria include its AEC-Q100 qualification, -40°C to +125°C operation, 5V ±1% output accuracy across temperature, 40V-tolerant enable input, and compatibility with 10µF ceramic output capacitance for stability in space-constrained automotive PCB layouts.
Technical Context
The ISL78301FVEBZ implements a high-voltage PMOS pass transistor architecture enabling low dropout and stable regulation down to 3V input during cold-crank events. Its internal error amplifier references a precision 1.223V bandgap, delivering tight 5.0V output tolerance (±1%) over full temperature and load range.
Enable logic is TTL/CMOS-compatible with 1.485V turn-on threshold and 0.975V turn-off threshold, supporting robust microcontroller interface. Protection circuitry includes foldback current limiting (175–410mA trip), thermal shutdown at +165°C with +20°C hysteresis, and 5kV HBM ESD rating-ensuring resilience in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% (4.95–5.05V) across -40°C to +125°C and 0.1–150mA load |
| Input Voltage Range | +3V to +40V - supports cold-crank (3V) and load-dump (40V) transients without dropout or damage |
| Quiescent Current | 22–28µA at no load - enables <100µA system standby power in always-on domains |
| Dropout Voltage | 295mV at 150mA - allows regulation from 5.3V input when VOUT = 5V, minimizing heat dissipation |
| Shutdown Current | 2–3.64µA with EN low - reduces parasitic drain during vehicle sleep mode |
| Thermal Protection | Shuts down at +165°C junction temp with +20°C hysteresis - prevents thermal runaway on HTSSOP exposed pad |
| PSRR | 55dB at 100Hz - suppresses battery ripple and alternator noise in sensitive analog subsystems |
Pinout & Package
ISL78301FVEBZ is housed in a thermally enhanced 14-lead HTSSOP package (M14.173B) with an exposed thermal pad requiring solder connection to PCB ground plane for effective heat dissipation and junction temperature control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2 (IN) | Input voltage supply | Accepts 3–40V; requires ≥0.1µF ceramic decoupling close to pin for stability |
| 7 (EN) | Enable control input | TTL/CMOS-compatible; >1.485V enables regulation, <0.975V forces 2µA shutdown |
| 8 (GND) | Analog and power ground | Reference node for all internal circuitry; must connect directly to low-impedance PCB ground plane |
| 12 (ADJ/NC) | Feedback reference terminal | No-connect for 5V fixed version; internally tied to 1.223V reference - leave floating or grounded |
| 14 (OUT) | Regulated 5V output | Delivers up to 150mA; requires 10µF ceramic capacitor to GND for loop stability |
| EPAD | Thermal and electrical ground | Exposed copper pad beneath package - must be soldered to PCB GND plane for θJC = 5°C/W |
Key Features
| Feature | Design Value |
|---|---|

| Stable with 10µF ceramic output cap | Eliminates need for costly tantalum or aluminum electrolytic capacitors in compact designs |
| Low 295mV dropout at 150mA | Permits use in 5.5V nominal systems while maintaining regulation through brownout |
| 5kV HBM ESD rating | Withstands electrostatic discharge during assembly and field service without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B6750QDGNRQ1 | 5V fixed, 150mA, 25µA IQ, but higher 400mV dropout at 150mA; requires 2.2µF min COUT | Lacks 40V EN tolerance; rated only to +105°C ambient (not +125°C) | Preferred where lower cost and TI ecosystem integration outweigh need for extreme cold-crank margin and full AEC-Q100 Grade 1 temp range |
| NCP163ASN50T2G | 5V fixed, 150mA, 20µA IQ, 300mV dropout, but only 24V max VIN and no AEC-Q100 qualification | Not qualified for automotive under-hood use; limited to cabin or industrial applications | Suitable for non-automotive embedded systems needing similar IQ and output specs without 40V transient immunity or extended temperature validation |
Compared with TPS7B6750QDGNRQ1 and NCP163ASN50T2G, the ISL78301FVEBZ uniquely combines 40V input tolerance, -40°C to +125°C AEC-Q100 Grade 1 qualification, and 40V-tolerant enable-making it the only option validated for direct battery connection in demanding under-hood and always-on automotive subsystems.

FAQ
What is the maximum input voltage the ISL78301FVEBZ can withstand during load-dump events?
The ISL78301FVEBZ has an absolute maximum input voltage rating of +45V and is designed to operate continuously at +40V, making it fully compatible with ISO 7637-2 Load Dump Pulse 5a (up to 40V for 400ms). This ensures reliable regulation during alternator load-dump transients without shutdown or damage, a key requirement for direct-battery-connected automotive modules.
Does the ISL78301FVEBZ require an external resistor divider to set the output voltage?
No, the ISL78301FVEBZ is the fixed 5.0V output variant and does not require an external resistor divider. Pin 12 (ADJ/NC) is internally connected to the 1.223V reference and is unused; it may be left floating or tied to GND. Only the adjustable version (ISL78301FVECZ) uses this pin for feedback configuration.
What is the recommended output capacitor value and type for stable operation of the ISL78301FVEBZ?
The ISL78301FVEBZ is specified for stable operation with a minimum 10µF ceramic capacitor (X5R or X7R dielectric) placed directly between the OUT (pin 14) and GND (pin 8). The capacitor's ground connection must route to the GND pin-not a distant ground plane-to minimize ESL and ensure phase margin. Tantalum or electrolytic capacitors are not required or recommended.
How does the enable function of the ISL78301FVEBZ behave during power sequencing?
The ISL78301FVEBZ enables regulation within 1.65–1.93ms after EN rises above 1.485V (VEN_H), and disables within microseconds when EN falls below 0.975V (VEN_L). Its 40V-tolerant EN pin allows direct connection to 12V battery or 5V MCU outputs without level shifters, simplifying power sequencing in multi-rail automotive systems.
Is the ISL78301FVEBZ compatible with lead-free reflow processes?
Yes, the ISL78301FVEBZ is Pb-free and RoHS-compliant, with a matte tin (e3) termination finish qualified for standard Pb-free reflow profiles per IPC/JEDEC J-STD-020. Its M14.173B HTSSOP package supports peak reflow temperatures up to 260°C, and moisture sensitivity level (MSL) information is documented in the product information page.
