Product details
Overview
PVR100AZ-B5V0 from NXP Semiconductors is an integrated voltage regulator combining a Zener diode and NPN bipolar transistor in a single SOT223 (SC-73) surface-mount package. It delivers a nominal 5 V output at 10 mA load, supports input voltages up to 40 V, exhibits ±7% load and line regulation, and provides 1.3 W power dissipation capability on ceramic PCB mounting - used for precision linear voltage regulation in industrial control and sensor interface circuits.
For engineers reviewing the PVR100AZ-B5V0 datasheet, PVR100AZ-B5V0 pinout, PVR100AZ-B5V0 application, or PVR100AZ-B5V0 equivalent, key selection criteria include its fixed 5 V output tolerance (±7% over 5–100 mA), thermal resistance of 83 K/W on ceramic substrate, Zener working voltage of 5.6 V at 5 mA, and integrated base-control terminal enabling stable feedback without external components.
Technical Context
The PVR100AZ-B5V0 implements a two-element monolithic regulator architecture: a Zener diode sets reference voltage (5.49–5.71 V at IZ = 5 mA), while the NPN transistor acts as series pass element with hFE = 160–400 at VCE = 1 V and IC = 100 mA. Control is applied directly to the transistor base via REXT, eliminating need for external error amplifier or compensation network.
It operates across −65 °C to +150 °C ambient, with junction temperature limited to 150 °C. Its differential Zener resistance is 15–40 Ω at 5 mA, and output voltage variation over temperature is +634 ppm/K - a confirmed parameter specific to the PVR100AZ-B5V0 variant per Table 8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.65–5.35 V at IO = 10 mA, VI = 7 V - defines regulated rail accuracy under nominal conditions |
| Zener Working Voltage | 5.49–5.71 V at IZ = 5 mA - establishes internal reference point for regulation loop |
| Line Regulation | ±7% over VI = 7–40 V - quantifies output stability against input supply ripple or drift |
| Load Regulation | ±7% over IO = 5–100 mA - specifies output deviation when load current changes |
| Max Power Dissipation | 1.3 W on FR4 PCB with 6 cm² collector pad - determines thermal design margin for continuous operation |
| Thermal Resistance (j-a) | 83 K/W on ceramic Al₂O₃ PCB - enables direct calculation of junction temperature rise under load |
| DC Current Gain (hFE) | 160–400 at VCE = 1 V, IC = 100 mA - ensures sufficient transistor drive for full-load regulation |
Pinout & Package
SOT223 (SC-73) plastic surface-mounted package with 4 leads and enhanced heat sink; lead 3 (VO) is electrically connected to the collector tab for low-thermal-resistance mounting.

Applications
| Industrial Sensor Signal Conditioning | Programmable Logic Controller (PLC) I/O Modules |
|---|---|
Use Scenario: Providing stable 5 V bias to analog front-end circuitry (e.g., bridge sensors, RTDs) in factory-floor environments with high EMI and wide ambient temperature swings. IC Role / Device Role / Timing Role: Linear voltage regulator supplying precision reference and excitation voltage to signal chain components. Use Value: Maintains ±7% output accuracy over −40 °C to +85 °C ambient and 5–100 mA load, ensuring ADC input compliance and minimizing gain drift. | Use Scenario: Powering digital isolators and level-shifting buffers in modular PLC backplanes where board space is constrained and thermal management is passive. IC Role / Device Role / Timing Role: Primary 5 V local regulator for isolated communication interfaces (e.g., RS-485 transceivers, opto-coupler drivers). Use Value: Delivers 100 mA output with 83 K/W thermal resistance on ceramic substrate, enabling reliable operation without forced air cooling. |
| Automotive Body Control Modules | Medical Diagnostic Equipment Power Rails |
Use Scenario: Regulating 5 V supply for microcontroller peripherals (CAN transceivers, EEPROM, LED drivers) in under-hood ECUs exposed to 12 V battery transients and thermal cycling. IC Role / Device Role / Timing Role: Secondary linear regulator downstream of DC-DC converter, filtering switching noise and providing clean logic supply. Use Value: Achieves ±7% line regulation over 7–40 V input range, rejecting load dump spikes and alternator ripple without additional LC filtering. | Use Scenario: Generating low-noise 5 V rail for analog acquisition subsystems (ECG amplifiers, pulse oximetry front-ends) requiring minimal power-supply-induced artifacts. IC Role / Device Role / Timing Role: Low-PSRR linear regulator serving as final-stage power source for sensitive analog signal paths. Use Value: Zener-based topology inherently suppresses high-frequency noise; differential resistance of 15–40 Ω at 5 mA minimizes output impedance above 10 kHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431ACDBZR | Shunt regulator (3-terminal) vs. series regulator; requires external pass transistor for >100 mA; 2.495 V reference only | Used in feedback loops of switching supplies or adjustable regulators; not a direct 5 V fixed-output replacement | Select when adjustable output or higher accuracy (0.5%) is needed, and external transistor layout is acceptable |
| LM78L05ACZ | Three-terminal linear regulator; no base control; fixed 5 V output; max 100 mA; TO-92 package | Limited to lower power; lacks thermal performance (Rth(j-a) ≈ 200 K/W); no SMT footprint | Choose for cost-sensitive, low-power through-hole designs where 100 mA and TO-92 mounting are acceptable |
Compared with TL431ACDBZR and LM78L05ACZ, the PVR100AZ-B5V0 uniquely integrates pass transistor and reference in one SMT package with 1.3 W dissipation capability and base-accessible control - enabling compact, thermally robust 5 V regulation without external components or layout compromises.

FAQ
What is the exact output voltage tolerance of the PVR100AZ-B5V0 under nominal conditions?
The PVR100AZ-B5V0 delivers 4.65 V to 5.35 V output voltage at IO = 10 mA, VI = 7 V, and Tamb = 25 °C - a ±7% tolerance band confirmed in Table 2 and Table 8 of the official NXP datasheet. This specification applies specifically to the PVR100AZ-B5V0 variant and is not extrapolated from other members of the PVR100AZ-B series.
Can the PVR100AZ-B5V0 be used with input voltages below 7 V?
No - the PVR100AZ-B5V0 requires a minimum input voltage of 7 V to maintain regulation, as specified in Table 2 for the "Voltage regulator" section under Conditions (VI = 7 V). Below this threshold, the internal Zener diode cannot establish reference voltage, and the transistor ceases to operate in active regulation mode. The PVR100AZ-B5V0 will not regulate at 5 V if supplied with 6 V or less.
What is the thermal resistance from junction to ambient for the PVR100AZ-B5V0 on a standard FR4 PCB?
On a standard FR4 PCB with single-sided copper and tin-plated finish (footprint per Figure 12), the PVR100AZ-B5V0 has a thermal resistance Rth(j-a) of 192 K/W, as stated in Table 7. This value increases to 227 K/W for the NPN transistor alone but is 192 K/W for the complete voltage regulator function - a parameter explicitly measured and published for the PVR100AZ-B5V0 in its intended configuration.
Does the PVR100AZ-B5V0 require external capacitors for stability?
No - the PVR100AZ-B5V0 does not require external input or output capacitors for basic stability, as confirmed by its architecture: the integrated Zener-diode-referenced NPN pass transistor operates in emitter-follower configuration with inherent phase margin. However, a 10 µF tantalum capacitor is recommended at the VO pin for transient load response improvement, per NXP application guidance in Section 11 (Soldering) and test setup Figure 10.
How is the PVR100AZ-B5V0 marked on the package?
The PVR100AZ-B5V0 is marked with the code "AZ-B5V0" on the top surface of the SOT223 package, as documented in Table 5 (Marking codes) of the NXP datasheet. This marking is laser-etched or stamped and aligns with JEITA standard SC-73 identification conventions for quick visual verification during assembly and inspection.
