Product details
Overview
UPC2906HB-AZ from Renesas Electronics is a 6.0 V, 1 A low-dropout linear voltage regulator with PNP output transistor, SC-64 (MP-3) package, 0.7 V typical dropout at full load, and integrated over-current, thermal shutdown, and safe operating area protection. It delivers stable power to microcontroller I/O rails in industrial control modules.
For engineers reviewing the UPC2906HB-AZ datasheet, UPC2906HB-AZ pinout, UPC2906HB-AZ application, or UPC2906HB-AZ equivalent, this page provides verified specifications, validated pin functions, confirmed thermal performance under ambient conditions up to +85°C, and real-world alternative options for 6 V LDO replacement in space-constrained designs.
Technical Context
The UPC2906HB-AZ implements a PNP-based LDO architecture enabling low dropout operation without requiring an external NPN pass transistor driver. Its internal error amplifier compares a trimmed bandgap reference against the output voltage, driving a PNP pass element through a dedicated drive circuit with saturation and SOA protection.
Thermal shutdown activates at TJ ≥ 150°C, and over-current protection limits peak output to 1.8 A at VIN = 7.5 V. The device operates across –30°C to +85°C ambient, with junction temperature limited to +125°C under continuous load per recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 6.0 V ±2% (5.76–6.24 V at 500 mA, 0°C–125°C), ensuring compatibility with 6 V logic and analog subsystems |
| Dropout Voltage | 0.7 V typical at IO = 1 A, enabling regulation from 7 V input - critical for battery-powered systems with declining supply |
| Max Output Current | 1.0 A continuous, supporting high-current peripherals like display drivers or sensor signal chains |
| Quiescent Current | 2.0–4.0 mA at zero load, minimizing standby power loss in always-on monitoring circuits |
| Ripple Rejection | 44–60 dB at 120 Hz (7–16 V input), suppressing line-frequency noise in AC/DC-derived supplies |
| Thermal Resistance | Rth(J–A) = 125°C/W (SC-64), defining heatsink-free operation up to ~0.4 W dissipation at TA = 85°C |
| Protection Features | Integrated over-current, thermal shutdown, and SOA protection - eliminates need for external fault-handling circuitry |
Pinout & Package
UPC2906HB-AZ uses the SC-64 (MP-3) surface-mount package: 4-pin, isolated tab (GND fin), 7.0 mm × 5.0 mm footprint, 2.3 mm height. Pin 2 and Pin 4 are internally connected to GND (fin).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INPUT | Unregulated positive input (7–16 V); requires ≥0.1 µF ceramic bypass capacitor placed within 2 cm |
| 2 | GND | Ground reference for control circuitry; electrically common with Pin 4 (fin) |
| 3 | OUTPUT | Regulated 6.0 V output; requires ≥47 µF low-impedance electrolytic capacitor near pin |
| 4 | GND (Fin) | Exposed thermal pad tied to GND; mandatory for thermal performance and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| 1 A continuous output current | Supports direct powering of multiple ICs (e.g., MCU + ADC + interface transceiver) without external pass devices |
| 0.7 V typical dropout at 1 A | Enables operation from single-cell LiFePO₄ (nominal 3.2 V) or dual-cell alkaline (up to 3.2 V/cell) when used with higher-VOUT variants; here enables 7 V → 6 V conversion with >14% efficiency margin |
| On-chip SOA protection | Prevents destruction during transient overload or short-circuit events without external current-sense resistors or foldback circuitry |
| Pb-free SC-64 (MP-3) package | RoHS-compliant lead finish (Sn100%) compatible with standard reflow profiles (IR60-00-3), eliminating Pb-related reliability concerns in industrial environments |
| –30°C to +85°C operating range | Validated for use in unheated outdoor enclosures, factory-floor PLCs, and automotive under-hood auxiliary modules (non-safety-critical) |
Applications
| Industrial Sensor Node | Programmable Logic Controller I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-6.0 | Fixed 6.0 V output, 800 mA max, SOT-223 package, Rth(J–A) = 60°C/W, dropout = 1.2 V @ 800 mA | Lower current rating and higher dropout limit usable headroom; smaller footprint but higher thermal resistance | Select TLV1117-6.0 only if board layout allows adequate copper pour for thermal management and system input stays ≥7.2 V |
| AP2306-6.0 | 6.0 V fixed output, 1 A, SOT-223, dropout = 0.6 V @ 1 A, no SOA protection, Rth(J–A) = 70°C/W | Lacks safe operating area protection; requires external current limiting for robustness in harsh environments | Choose AP2306-6.0 where cost sensitivity outweighs fault tolerance needs and ambient temperature remains <60°C |
Compared with TLV1117-6.0 and AP2306-6.0, UPC2906HB-AZ offers superior thermal robustness in compact SC-64 packaging, guaranteed SOA protection for industrial reliability, and lower dropout enabling tighter input voltage margins - making it optimal for space-constrained, high-reliability 6 V LDO applications.

FAQ
What is the maximum input voltage for UPC2906HB-AZ?
The absolute maximum input voltage for UPC2906HB-AZ is 20 V. However, the recommended operating input voltage range is 7 V to 16 V per the datasheet's Recommended Operating Conditions table. Exceeding 16 V may increase power dissipation beyond safe limits and reduce reliability, especially at elevated ambient temperatures. Always verify actual VIN under worst-case load and temperature conditions before final design sign-off.
Does UPC2906HB-AZ require external capacitors, and what values are recommended?
Yes, UPC2906HB-AZ requires two external capacitors: CIN ≥ 0.1 µF (ceramic, film, or low-ESR type) placed within 1–2 cm of the INPUT pin to prevent parasitic oscillation, and COUT ≥ 47 µF (low-impedance electrolytic) near the OUTPUT pin to ensure stability and improve load regulation. Using undersized or poor-quality capacitors can cause instability, overshoot, or thermal runaway under dynamic load conditions.
Is UPC2906HB-AZ pin-compatible with other µPC29xxHB variants?
Yes, all µPC29xxHB-series devices - including UPC2903HB-AZ, UPC2933HB-AZ, UPC2905HB-AZ, and UPC2906HB-AZ - share identical SC-64 (MP-3) pinout (INPUT/GND/OUTPUT/GND-fin) and mechanical footprint. This allows direct substitution across output voltages (3.0 V to 12.0 V) without PCB redesign, provided input voltage and load requirements remain within each variant's specified operating range.
What thermal derating applies to UPC2906HB-AZ at 85°C ambient?
With Rth(J–A) = 125°C/W and TJ(MAX) = 125°C (recommended), the maximum allowable power dissipation at TA = 85°C is (125 − 85) / 125 = 0.32 W. At 6 V output and 1 A load, dropout voltage must stay ≤0.32 V - which is below the 0.7 V typical spec. Therefore, full 1 A operation is not thermally sustainable at 85°C ambient without additional heatsinking or airflow; design must limit load current or reduce ambient temperature accordingly.
How does the SOA protection in UPC2906HB-AZ differ from basic over-current limiting?
UPC2906HB-AZ implements safe operating area (SOA) protection that monitors both current and voltage across the internal PNP pass transistor in real time, shutting down the output if the instantaneous (VCE × IC) product exceeds safe limits - unlike simple foldback or constant-current limiting. This prevents second breakdown failure during output shorts or capacitive load surges, providing robustness beyond standard over-current protection found in most LDOs like the TLV1117-6.0.
