Product details
Overview
PVR100AZ-B3V0 from NXP Semiconductors is a monolithic integrated voltage regulator combining a Zener diode and NPN bipolar transistor in a single SOT223 (SC-73) surface-mount package. It delivers a nominal 3.0 V output at 10 mA load, supports input voltages from 5 V to 40 V, exhibits ±10% line regulation, and provides 1.3 W total power dissipation capability on ceramic PCB mounting - used for precision linear voltage regulation in industrial sensor interfaces and low-power microcontroller supply rails.
For engineers reviewing the PVR100AZ-B3V0 datasheet, PVR100AZ-B3V0 pinout, PVR100AZ-B3V0 application, or PVR100AZ-B3V0 equivalent, key selection considerations include its fixed 3.0 V output tolerance (±10%), thermal resistance of 83 K/W on ceramic substrate, differential Zener resistance of 85–90 Ω at 5 mA, temperature coefficient of −2.4 mV/K, and compatibility with standard SOT223 reflow footprints.
Technical Context
The PVR100AZ-B3V0 implements a two-element series-pass regulator architecture: the Zener diode sets reference voltage (3.6 V typical at IZ = 5 mA), while the integrated NPN transistor acts as active pass element with DC current gain (hFE) ranging from 160 to 400 at VCE = 1 V and IC = 100 mA. Control current (Ictrl) is specified at 6.5 mA under nominal operating conditions.
Regulation performance is defined across ambient temperatures from −55 °C to +150 °C, with relative output voltage variation over temperature (ΔVO/(VO×ΔTamb)) at −78 × 10−6/K and load regulation of ±10% over 5–100 mA output current. Input-to-output voltage headroom is 2 V minimum (VI = 5 V for VO = 3 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V nominal (2.7–3.3 V min/max at IO = 10 mA), enabling stable biasing of 3.3 V logic with margin |
| Zener Working Voltage | 3.6 V typical at IZ = 5 mA (3.53–3.67 V range), directly setting internal reference point |
| Line Regulation | ±10% over VI = 5–40 V, limiting sensitivity to unregulated input rail fluctuations |
| Load Regulation | ±10% over IO = 5–100 mA, ensuring consistent output under varying downstream current demand |
| Total Power Dissipation | 1.3 W maximum on ceramic PCB (Al2O3), supporting medium-power linear regulation without external heatsink |
| Differential Zener Resistance | 85–90 Ω at IZ = 5 mA, determining small-signal impedance and ripple rejection capability |
| Temperature Coefficient | −2.4 mV/K typical, indicating negative drift with rising ambient temperature |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431ACDBZR | Adjustable shunt regulator (2.5 V reference); requires external pass transistor and feedback resistors; lower max output current (100 mA) | Used in feedback loops of switching regulators or adjustable LDOs; not a drop-in replacement | Select when design requires programmable output or higher precision (0.5% initial tolerance vs. PVR100AZ-B3V0's ±10%) |
| LM317LZ/NOPB | Adjustable linear regulator; requires two external resistors; 1.25 V reference; 100 mA max output; TO-92 package | Typically used in low-cost, low-current applications where adjustability and through-hole assembly are acceptable | Choose when board space allows TO-92 and output voltage must be set externally; not suitable for SMT-only designs |
Compared with TL431ACDBZR and LM317LZ/NOPB, the PVR100AZ-B3V0 offers factory-set 3.0 V output, integrated pass transistor, SOT223 thermal performance, and no external components - simplifying BOM and layout at the cost of adjustability and tighter initial tolerance.

FAQ
What is the maximum input voltage the PVR100AZ-B3V0 can handle?
The PVR100AZ-B3V0 supports a maximum input voltage of 40 V under normal operating conditions, as specified in the line regulation test condition (5 V ≤ VI ≤ 40 V). Its NPN transistor has a VCEO rating of 45 V (open base), providing 5 V margin against transient overvoltage events. Operation beyond 40 V violates the recommended operating conditions and may degrade regulation accuracy or reliability.
Does the PVR100AZ-B3V0 require external components to function?
No, the PVR100AZ-B3V0 requires no external components to deliver its nominal 3.0 V output. The integrated Zener diode and NPN transistor form a complete series-pass regulator. Only input (VI), ground (GND), and output (VO) connections are needed; the REXT pin is internally connected and not user-accessible. This distinguishes PVR100AZ-B3V0 from adjustable regulators like TL431 or LM317 that require external resistors.
What is the thermal resistance of the PVR100AZ-B3V0 on a standard FR4 PCB?
When mounted on a standard FR4 PCB with single-sided copper and tin plating (no extended heat sink), the PVR100AZ-B3V0 has a junction-to-ambient thermal resistance (Rth(j-a)) of 192 K/W. This value increases to 96 K/W with a 6 cm² collector mounting pad and further improves to 83 K/W on ceramic (Al2O3) substrate - critical for calculating safe operating area under sustained load.
Can the PVR100AZ-B3V0 be used in automotive applications?
The PVR100AZ-B3V0 operates across −55 °C to +150 °C ambient temperature and withstands 45 V collector-emitter voltage, making it suitable for non-safety-critical automotive body electronics such as door modules and seat controls. However, it is not AEC-Q100 qualified, lacks automotive-specific qualification testing, and should not be used in safety-related systems (e.g., airbag, braking, ADAS) without additional validation by the end customer.
What is the Zener diode's differential resistance at 5 mA for the PVR100AZ-B3V0?
The Zener diode in the PVR100AZ-B3V0 exhibits a differential resistance (rdif) of 85–90 Ω at IZ = 5 mA, as specified in Table 8 of the datasheet. This parameter directly affects ripple rejection and dynamic regulation response - lower rdif values indicate stiffer voltage reference behavior under varying current conditions.
