Product details
Overview
UPC2910T-AZ from Renesas Electronics is a 10 V, 1 A low-dropout linear voltage regulator with PNP output transistor, SC-63 (MP-3Z) surface-mount package, 0.7 V typical dropout at 1 A, and integrated over-current, thermal, and safe operating area protection. It delivers stable power to microcontroller I/O rails in industrial control modules.
For engineers reviewing the UPC2910T-AZ datasheet, UPC2910T-AZ pinout, UPC2910T-AZ application, or UPC2910T-AZ equivalent, key selection criteria include dropout voltage at full load, thermal resistance (12.5°C/W junction-to-case), quiescent current variation across temperature, and Pb-free reflow compatibility per IR60-00-3 profile.
Technical Context
The UPC2910T-AZ uses a PNP pass transistor architecture enabling low dropout operation without requiring an external NPN driver stage. Its internal error amplifier compares output voltage against a precision reference and drives the PNP emitter follower to maintain regulation under varying load and input conditions.
Protection functions are fully integrated: thermal shutdown activates above +150°C junction temperature; over-current limiting responds within microseconds to short-circuit events; and SOA protection prevents secondary breakdown during transient overload. No external components are required for basic operation beyond input/output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.0 V ±5% (guaranteed over –30°C to +125°C junction temp, 0–1 A load) |
| Dropout Voltage | 0.7 V typical at 1 A (enables regulation with only 11 V input; critical for battery-powered systems) |
| Output Current | 1.0 A continuous (supports logic-level peripherals, sensors, and small actuators) |
| Quiescent Current | 2.0–4.0 mA at zero load; ≤60 mA at 1 A (low standby power for always-on applications) |
| Thermal Resistance | 12.5°C/W junction-to-case (requires heatsink design for >1 W dissipation in ambient >60°C) |
| Ripple Rejection | 40 dB at 120 Hz, 11–18 V input (suppresses AC line noise in offline SMPS-derived supplies) |
| Noise Voltage | 180 µVr.m.s. (10 Hz–100 kHz; suitable for analog sensor front-ends) |
Pinout & Package
UPC2910T-AZ uses the SC-63 (MP-3Z) 4-pin surface-mount package with isolated GND fin. Pin 2 is cut; pins 2 and 4 share GND connection via the exposed metal fin, which serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Unregulated input supply | Accepts 11–18 V DC; must be decoupled with ≥0.1 µF film capacitor near pin |
| 2 (GND) | Ground reference (cut lead) | Not electrically connected; mechanical placeholder for alignment |
| 3 (OUTPUT) | Regulated 10 V output | Delivers up to 1 A; requires ≥47 µF low-impedance electrolytic capacitor |
| 4 (GND / Fin) | Power ground and thermal interface | Exposed metal pad; must be soldered to PCB copper pour for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 0.7 V typical at 1 A enables use in 12 V systems with minimal headroom loss |
| Integrated SOA protection | Prevents secondary breakdown during output short-circuit or high-VCE transients |
| Pb-free reflow compliance | Rated for IR60-00-3 profile (260°C peak, ≤60 s at ≥220°C) without degradation |
| Thermal shutdown | Auto-recovery after junction cools below +150°C; no latch-up behavior |
| Input reverse polarity protection | Internal diode blocks damage if input is accidentally reversed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-10CPK | 1.2 V dropout at 1 A; 800 mA max output; SOT-223 package; higher RθJA (60°C/W) | Limited to lower-power applications; less suitable for sustained 1 A loads in compact enclosures | Choose when board space is constrained and thermal budget permits higher dropout |
| LD1085V10 | NPN-based architecture; 1.5 V dropout at 1 A; TO-220 package; no integrated SOA protection | Requires external SOA circuitry for robustness; higher minimum input voltage needed | Choose when legacy TO-220 footprint compatibility is mandatory and thermal mass is available |
Compared with TLV1117-10CPK and LD1085V10, UPC2910T-AZ offers superior thermal performance (12.5°C/W vs. 60°C/W or 50°C/W), lower dropout (0.7 V vs. 1.2 V or 1.5 V), and built-in SOA protection-making it optimal for space-constrained, high-reliability 1 A applications where input headroom is limited.

FAQ
What is the maximum input voltage rating for UPC2910T-AZ?
The absolute maximum input voltage for UPC2910T-AZ is 20 V. However, the recommended operating range is 11 V to 18 V per the datasheet's Recommended Operating Conditions table. Exceeding 18 V may degrade long-term reliability or trigger thermal shutdown under load, so designs should maintain VIN ≤ 18 V for continuous operation. The UPC2910T-AZ datasheet specifies this limit to ensure safe operation of the internal PNP pass transistor and protection circuitry.
Does UPC2910T-AZ require external capacitors, and what values are recommended?
Yes, UPC2910T-AZ requires both input and output capacitors for stability. A minimum 0.1 µF film or ceramic capacitor must be placed directly at the INPUT pin to prevent parasitic oscillation; a 47 µF or larger low-impedance electrolytic capacitor is required at the OUTPUT pin to suppress load transients and improve regulation. These values are specified in the Typical Connection diagram and Electrical Characteristics section of the UPC2910T-AZ datasheet.
How does the thermal shutdown feature operate in UPC2910T-AZ?
The UPC2910T-AZ incorporates an internal thermal shutdown circuit that disables the output when junction temperature exceeds +150°C. Once the die cools below the hysteresis threshold (~135°C), regulation automatically resumes without manual reset. This behavior is confirmed in the Absolute Maximum Ratings note and Typical Characteristics curves of the UPC2910T-AZ datasheet, ensuring self-protection during overload or inadequate heatsinking.
Is UPC2910T-AZ compatible with lead-free reflow processes?
Yes, UPC2910T-AZ is explicitly qualified for Pb-free reflow per the IR60-00-3 profile: peak package surface temperature ≤260°C, duration ≤60 seconds at ≥220°C, and up to three reflow cycles. This is documented in the Recommended Soldering Conditions section of the UPC2910T-AZ datasheet, distinguishing it from non-AZ variants that follow IR35-00-3.
What is the output voltage tolerance of UPC2910T-AZ over temperature and load?
The UPC2910T-AZ guarantees output voltage within ±5% (9.5 V to 10.5 V) across the full operating junction temperature range (–30°C to +125°C) and full load range (0 A to 1 A), as specified in the Electrical Characteristics table for µPC2910. This tolerance includes combined effects of line regulation (≤100 mV), load regulation (≤100 mV), and temperature coefficient (2.1 mV/°C).
