Product details
Overview
UPC29M07HB-AZ from Renesas Electronics is a three-terminal low-dropout positive voltage regulator with PNP output transistor, delivering 0.5 A output current at 7.0 V nominal output, 0.5 V typical dropout voltage (IO = 0.5 A), and integrated over-current, thermal, and safe operating area protection. It serves as a primary power supply regulator in industrial control modules requiring stable 7 V rail generation from 8–16 V input sources.
For engineers reviewing the UPC29M07HB-AZ datasheet, UPC29M07HB-AZ pinout, UPC29M07HB-AZ application, or UPC29M07HB-AZ equivalent, key selection criteria include dropout performance at full load, thermal resistance (Rth(J-C) = 12.5°C/W), SC-64 package footprint compatibility, and Pb-free compliance for RoHS-constrained designs.
Technical Context
The UPC29M07HB-AZ implements a PNP-based LDO architecture with internal reference voltage, error amplifier, drive circuit, and multiple protection blocks-including thermal shutdown, saturation protection, and safe operating area (SOA) monitoring-enabling robust operation without external components beyond input/output capacitors. Its design targets low-noise, high-stability regulation where NPN-based regulators exhibit excessive power dissipation.
It operates across –30°C to +85°C ambient temperature, supports input voltages from 8 V to 16 V, and maintains ±3% output voltage accuracy (6.65–7.35 V) over full load (0–0.5 A) and junction temperature (0–125°C). Dropout voltage remains ≤1.0 V across all specified conditions, enabling efficient use in margin-constrained power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 7.0 V nominal; ±3% tolerance (6.65–7.35 V) over 0–0.5 A load and 0–125°C junction temperature - ensures stable biasing for 7 V logic or analog subsystems. |
| Dropout Voltage | 0.5 V typical / ≤1.0 V max at 0.5 A - enables operation with only 0.5 V headroom above output, critical for battery-powered or low-input-voltage systems. |
| Output Current | 0.5 A continuous - sufficient to power microcontrollers, sensors, and interface ICs in compact industrial modules. |
| Quiescent Current | 2.0–4.0 mA at zero load; ≤30 mA at 0.5 A - minimizes no-load power loss while maintaining regulation under full load. |
| Thermal Resistance | Rth(J-C) = 12.5°C/W - defines heatsink requirement: ~7.5°C/W heatsink needed to sustain 0.5 A at TA = 85°C with TJ ≤ 125°C. |
| Noise Voltage | 147 µVr.m.s. (10 Hz–100 kHz) - low enough for analog signal chains and precision ADC references without additional filtering. |
| Ripple Rejection | 40–56 dB at 120 Hz - suppresses line-frequency ripple from unregulated DC supplies, improving PSRR in sensitive analog stages. |
Pinout & Package
UPC29M07HB-AZ uses the SC-64 (MP-3) surface-mount package: 4-pin, isolated tab, 7.0 mm × 5.0 mm × 2.3 mm body, with GND connected to both Pin 2 and the exposed metal fin (Pin 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INPUT | Unregulated DC input (8–16 V); requires ≥0.1 µF ceramic capacitor placed within 1–2 cm to prevent parasitic oscillation. |
| 2 | GND | Analog and power ground reference; electrically common with Pin 4 (fin) - must be connected to low-impedance PCB ground plane. |
| 3 | OUTPUT | Regulated 7.0 V output; requires ≥47 µF low-ESR electrolytic capacitor near pin to ensure stability and transient response. |
| 4 | GND (Fin) | Exposed metal tab serving as secondary GND path and primary thermal conduction path to PCB copper - must be soldered to ≥2 cm² thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| PNP output transistor architecture | Reduces power dissipation by >40% vs. comparable NPN regulators - extends thermal margin in sealed enclosures. |
| Integrated SOA protection | Prevents destructive second breakdown during short-circuit or capacitive load transients - eliminates need for external current-limiting resistors. |
| On-chip thermal shutdown | Activates at TJ ≥ 150°C and holds output off until junction cools to ~135°C - provides self-recovery fault tolerance without system-level intervention. |
| Pb-free (AZ suffix) | Meets EU RoHS Directive; Sn100% plating on external electrodes - compatible with lead-free reflow profiles up to 260°C peak. |
| Low-output-noise design | 147 µVr.m.s. noise floor enables direct powering of op-amps, voltage references, and SAR ADCs without post-regulation filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-7.0 | Fixed 7.0 V output; 800 mA rated; 1.2 V dropout min at 800 mA; SOT-223 package; higher quiescent current (5–10 mA). | Higher output current capability but larger dropout limits use in ultra-low-headroom designs; SOT-223 requires more board area than SC-64. | Select TLV1117-7.0 when >0.5 A load or higher thermal mass is available; avoid if input voltage margin is <1.2 V. |
| LD1085V70 | Fixed 7.0 V output; 3 A rated; 1.5 V dropout min at 3 A; TO-220 package; no integrated SOA protection. | Designed for high-current applications; lacks on-chip safe operating area protection - requires external current limiting for short-circuit resilience. | Select LD1085V70 only for high-power systems with external fault management; not drop-in for space- or protection-constrained designs. |
Compared with TLV1117-7.0 and LD1085V70, UPC29M07HB-AZ delivers optimal balance of low dropout (0.5 V), integrated protection, and compact SC-64 footprint - making it preferred for thermally constrained, safety-aware industrial and medical edge nodes where reliability and board space are critical.

FAQ
What is the maximum input voltage rating for the UPC29M07HB-AZ?
The absolute maximum input voltage for UPC29M07HB-AZ is 20 V at TA = 25°C. However, the recommended operating input voltage range is 8 V to 16 V per the datasheet's Recommended Operating Conditions table. Exceeding 16 V may degrade long-term reliability or trigger thermal shutdown under load; sustained operation above 20 V risks permanent damage to the internal PNP pass transistor and protection circuitry.
Does the UPC29M07HB-AZ require external capacitors, and what values are mandatory?
Yes, UPC29M07HB-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 oscillation, and COUT ≥ 47 µF (low-impedance electrolytic) near the OUTPUT pin to ensure stability and improve load regulation. The datasheet explicitly states that omitting either capacitor risks instability, overshoot, or thermal runaway under dynamic load conditions.
How does the thermal protection in UPC29M07HB-AZ behave during overload?
UPC29M07HB-AZ features internal thermal shutdown that activates when junction temperature exceeds 150°C. Upon activation, the output is disabled and remains off until TJ drops to approximately 135°C, enabling automatic recovery. This behavior is confirmed in the Absolute Maximum Ratings note and Typical Characteristics curves - it is not hysteresis-limited or user-adjustable, and no external components are required to implement this protection.
Is the UPC29M07HB-AZ pin-compatible with other variants in the µPC29MxxHB family?
Yes, all µPC29MxxHB-series regulators - including UPC29M03HB-AZ, UPC29M05HB-AZ, and UPC29M07HB-AZ - share identical SC-64 (MP-3) pinout (Pin 1: INPUT, Pin 2: GND, Pin 3: OUTPUT, Pin 4: GND/FIN) and mechanical footprint. Output voltage is the sole functional difference; no PCB layout change is needed when substituting between these variants during design iteration or voltage-scaling upgrades.
What is the guaranteed output voltage accuracy of UPC29M07HB-AZ over temperature and load?
UPC29M07HB-AZ guarantees output voltage within ±3% (6.65 V to 7.35 V) across the full operating junction temperature range (0°C to 125°C) and full load range (0 A to 0.5 A), as specified in the Electrical Characteristics table for µPC29M07. This accuracy includes combined effects of line regulation (≤70 mV), load regulation (≤70 mV), and temperature coefficient (±0.7 mV/°C), verified under standardized test conditions (TJ = 25°C, VIN = 10 V, IO = 350 mA).
