Product details

Overview

PVR100AZ-B3V3 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, delivering a nominal 3.3 V output at 10 mA with ±7% line/load regulation, 3.9 V Zener working voltage at 5 mA, and 1.3 W total power dissipation capability on ceramic PCB mounting.

For engineers reviewing the PVR100AZ-B3V3 datasheet, PVR100AZ-B3V3 pinout, PVR100AZ-B3V3 application, or PVR100AZ-B3V3 equivalent, this device serves as a compact, thermally robust solution for low-current linear regulation where stable reference voltage generation and current amplification are co-integrated - critical for sensor biasing, analog front-end supply, and precision reference buffering.

Technical Context

The PVR100AZ-B3V3 implements a two-stage regulation architecture: a Zener diode establishes a precise reference voltage (3.82–3.98 V at I_Z = 5 mA), while the integrated NPN transistor (V_CEO = 45 V, h_FE = 160–400) provides current gain to drive load currents up to 100 mA. Its control input (REXT pin) connects directly to the transistor base, enabling external bias tuning.

Thermal performance is defined by mounting-dependent R_th(j-a): 83 K/W on ceramic PCB (Al₂O₃) and 96 K/W on FR4 with 6 cm² collector pad, supporting operation from −65 °C to +150 °C ambient. Output voltage stability is specified across temperature (−55 °C to +150 °C) and input variation (5.3 V ≤ V_I ≤ 40 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage (V_O)	3.07–3.53 V at I_O = 10 mA, V_I = 5.3 V - ensures stable 3.3 V rail for logic-level analog circuits under nominal load
Zener Working Voltage (V_Z)	3.82–3.98 V at I_Z = 5 mA - provides accurate internal reference for regulation loop
Line Regulation	±7% over 5.3 V ≤ V_I ≤ 40 V - limits output drift when input varies widely, e.g., unregulated DC bus
Load Regulation	±7% over 5–100 mA output - maintains voltage accuracy across typical sensor or op-amp supply ranges
Collector Current (I_C)	0.1 A max continuous - defines maximum load drive capability without external transistor stage
Thermal Resistance (R_th(j-a))	83 K/W on Al₂O₃ PCB - enables 1.3 W dissipation at T_amb = 25 °C, critical for high-reliability industrial designs
Operating Temperature	−65 °C to +150 °C - supports deployment in automotive under-hood or industrial motor-control environments

Pinout & Package

SOT223 (SC-73) plastic surface-mounted package with 4 leads and enhanced heat sink; standard footprint per Figure 11 (NXP document PVR100AZ-B_SER_1).

Pin/Terminal	Circuit Role	Design Meaning
1 - REXT	Transistor base connection	External resistor sets base bias current; determines regulation setpoint and thermal stability
2 - GND	Reference ground node	Common return for Zener cathode, transistor emitter, and output load - must be low-impedance
3 - V_O	Regulated output terminal	Delivers stabilized 3.3 V to load; internally sourced from transistor emitter
4 - V_I	Input voltage supply	Accepts 5.3–40 V input; powers both Zener and transistor stages via collector connection

Key Features

Feature	Design Value
Monolithic Zener + NPN integration	Eliminates discrete component matching and layout sensitivity - improves long-term reference stability
1.3 W power dissipation (ceramic PCB)	Supports higher load currents than standard Zener+transistor combos without heatsink
±7% line and load regulation	Meets tight tolerance requirements for analog signal conditioning and ADC reference supplies
−65 °C to +150 °C operating range	Enables use in extended-temperature industrial controllers and automotive body electronics
SC-73 (SOT223) package with thermal pad	Provides standardized reflow-compatible footprint and superior thermal transfer vs. SOIC or TO-92

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 IC (3-terminal); requires external pass transistor for >100 mA loads; 2.495 V reference, adjustable via resistors	Higher flexibility in output voltage setting but adds complexity and board area for discrete pass device	Select when adjustable output or tighter initial tolerance (±0.5%) is required; not drop-in for fixed 3.3 V
LM317LZ/NOPB	Adjustable linear regulator; 1.25 V reference, 100 mA max output; requires two external resistors	Lower quiescent current (80 µA vs. ~6.5 mA for PVR100AZ-B3V3) but lacks integrated Zener reference stability	Choose for ultra-low-power battery applications where 3.3 V is derived via resistor divider - not suitable for high-precision reference use

Compared with TL431ACDBZR and LM317LZ/NOPB, the PVR100AZ-B3V3 offers fixed 3.3 V output with monolithic integration, eliminating external components and layout dependencies - advantageous for space-constrained, high-reliability analog subsystems where reference stability outweighs adjustability.

FAQ

What is the exact output voltage tolerance of the PVR100AZ-B3V3 under nominal conditions?

The PVR100AZ-B3V3 delivers 3.07 V to 3.53 V at I_O = 10 mA and V_I = 5.3 V, corresponding to a ±7% tolerance around the nominal 3.3 V output. This specification holds across the full operating temperature range (−65 °C to +150 °C) and is verified per NXP's Product Data Sheet Rev. 01 (2006). The PVR100AZ-B3V3 achieves this using its integrated Zener reference and NPN pass transistor.

Can the PVR100AZ-B3V3 replace a discrete Zener diode and transistor combination?

Yes - the PVR100AZ-B3V3 is explicitly designed as a drop-in replacement for discrete Zener + NPN regulator circuits. It integrates matched components in a single SOT223 package, eliminating layout sensitivity, thermal tracking mismatches, and assembly steps. The PVR100AZ-B3V3 maintains identical functional pinout (REXT, GND, V_O, V_I) and electrical behavior, simplifying redesigns while improving long-term stability.

What is the maximum continuous load current supported by the PVR100AZ-B3V3?

The PVR100AZ-B3V3 supports up to 100 mA continuous output current, as confirmed by its load regulation specification (5–100 mA range) and NPN transistor collector current rating (I_C = 0.1 A). At 100 mA, output voltage remains within ±7% of 3.3 V when V_I = 5.3 V. Exceeding this current risks thermal overload unless mounted on ceramic PCB with full 1.3 W dissipation capability.

How does the PVR100AZ-B3V3 handle input voltage variations?

The PVR100AZ-B3V3 maintains output stability across a wide 5.3 V to 40 V input range, with line regulation limited to ±7%. This is achieved through its internal Zener reference and high-gain NPN transistor (h_FE = 160–400), which compensates for input fluctuations. The PVR100AZ-B3V3's relative output variation over input voltage is only 70 ppm/V - significantly tighter than standard 3-terminal regulators - making it suitable for unregulated DC bus applications.

Is the PVR100AZ-B3V3 RoHS-compliant and halogen-free?

Yes - the PVR100AZ-B3V3 complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. This is confirmed in NXP's official product documentation and packaging information (Table 9, PVR100AZ-B_SER_1), where the part is marked with standard RoHS-compliant tape-and-reel packing (code -115). The PVR100AZ-B3V3 meets environmental compliance requirements for industrial and automotive end equipment.
