Product details
Overview
MC33762DM-3030R2 from onsemi is a dual ultra-low-noise, low-dropout linear voltage regulator delivering two independent 3.0 V outputs with 80 mA nominal current per channel, 40 µVRMS noise (100 Hz–100 kHz), and 40 µs typical startup time - designed for RF-sensitive portable systems such as TDMA phones and VCO power supplies.
For engineers reviewing the MC33762DM-3030R2 datasheet, pinout, applications, or equivalent options, key selection criteria include dual-rail isolation, absence of external bypass capacitor requirement, fast transient recovery in burst-mode loads, and guaranteed 1.5% output precision across −40°C to +85°C.
Technical Context
The MC33762DM-3030R2 integrates two fully independent LDO regulators on separate dice, enabling >100 dB inter-channel isolation and eliminating crosstalk in noise-critical dual-rail applications. Each regulator features PNP pass transistors with antisaturation protection and load-transient improvement circuitry that actively suppresses undershoot during rapid load reappearance after zero-current decay.
Its architecture eliminates the need for an external bandgap bypass capacitor, achieving 150 nV/√Hz noise density at 100 Hz while maintaining 40 µs wake-up response - a trade-off resolved via internal noise-filtering topology rather than external capacitance. Static line regulation exceeds −75 dB, and ripple rejection is 70 dB at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±1.5% @ 25°C; ±3.0% over −40°C to +85°C - ensures stable bias for RF ICs without recalibration. |
| Noise Performance | 40 µVRMS (100 Hz–100 kHz), 150 nV/√Hz @ 100 Hz - meets stringent VCO phase-noise requirements without external filtering. |
| Dropout Voltage | 90 mV @ 30 mA, 160 mV @ 80 mA - enables operation from single-cell Li-ion (3.0 V min) with margin. |
| Startup Time | 40 µs typical from OFF to ON - supports burst-mode TDMA timing with no delay-induced frame loss. |
| Enable Threshold | 900 mV logic-high activation, 150 mV logic-low shutdown - compatible with 1.0 V platform GPIOs without level-shifting. |
| Ripple Rejection | 70 dB @ 1 kHz - suppresses switching regulator coupling into analog signal chains. |
| Thermal Shutdown | 125°C junction limit - protects against sustained overload in compact enclosures. |
Pinout & Package
Housed in an 8-pin Micro8 (Case 846A) surface-mount package with exposed thermal pad, the MC33762DM-3030R2 provides physical and electrical isolation between regulators via separate ground and supply pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND1 | Ground reference for Regulator 1 | Must be routed separately from GND2 to preserve >100 dB channel isolation. |
| 2 - EN1 | Enable input for Regulator 1 | 900 mV threshold allows direct interface with 1.0 V logic; no pull-up required. |
| 3 - GND2 | Ground reference for Regulator 2 | Independent return path prevents noise coupling from Regulator 2 into Regulator 1's ground. |
| 4 - EN2 | Enable input for Regulator 2 | Asynchronous control enables staggered power-up sequencing for EMI reduction. |
| 5 - VCC2 | Input supply for Regulator 2 | Requires local 1.0 µF ceramic decoupling; shared input with VCC1 not recommended. |
| 6 - VOUT2 | 3.0 V regulated output for Channel 2 | Stable with 1.0 µF output capacitor; ESR-insensitive (0–3 Ω). |
| 7 - VCC1 | Input supply for Regulator 1 | Separate input routing avoids supply interaction between channels. |
| 8 - VOUT1 | 3.0 V regulated output for Channel 1 | Same stability profile as VOUT2; dual outputs support split-rail RF subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent dice | Eliminates substrate coupling - critical for simultaneous Tx/Rx RF power supply isolation. |
| No external bypass capacitor | Reduces BOM count and PCB area while maintaining 40 µVRMS noise - unique among 3.0 V LDOs. |

| 1.0 V logic-compatible enable | 900 mV ON threshold supports direct connection to modern low-voltage microcontrollers and PMICs. |
| ESR-insensitive stability | Accepts 0–3 Ω output capacitor ESR - enables use of low-ESR ceramics without oscillation risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | Single-channel, 1 µVRMS noise (10 Hz–100 kHz), requires external bypass capacitor, 1.2 V to 6.8 V adjustable output. | Not dual-output; lacks integrated load-transient improvement for burst-mode loads. | Select only if single-rail ultra-low-noise performance is prioritized over channel count and burst robustness. |
| NCP1117DT33RKG | Single-channel, 3.3 V fixed, 42 µVRMS noise (10 Hz–100 kHz), no enable pin, 1.2 A max current, TO-252 package. | Higher noise floor, no ON/OFF control, no dual-isolation capability, unsuitable for space-constrained RF layouts. | Consider only for cost-sensitive non-RF applications where dual rail and fast wake-up are unnecessary. |
Compared with TPS7A4700RGWR and NCP1117DT33RKG, the MC33762DM-3030R2 uniquely delivers dual 3.0 V rails with integrated burst-mode transient suppression, 1.0 V logic compatibility, and no external bypass requirement - making it the only option qualified for TDMA handset RF power domains.

FAQ
What is the maximum input voltage rating for the MC33762DM-3030R2?
The MC33762DM-3030R2 has an absolute maximum input voltage of 12 V on both VCC1 and VCC2 pins, as specified in the Maximum Ratings table. Operation above this level risks permanent damage. For reliable 3.0 V output regulation, input must remain ≥ VOUT + 1.0 V (i.e., ≥ 4.0 V minimum), with recommended upper limit of 6.0 V for optimal thermal performance and dropout margin.
Does the MC33762DM-3030R2 require an external bypass capacitor for noise reduction?
No, the MC33762DM-3030R2 does not require an external bypass capacitor. Its proprietary low-noise architecture achieves 40 µVRMS (100 Hz–100 kHz) and 150 nV/√Hz noise density without one - a key differentiator confirmed in the datasheet's Features and Application Hints sections. Adding a bypass capacitor would degrade startup time and is neither necessary nor recommended.
How is channel isolation achieved between the two regulators in the MC33762DM-3030R2?
Channel isolation in the MC33762DM-3030R2 is achieved through physically separate silicon dice housed in a single Micro8 package, with dedicated ground (GND1/GND2), input (VCC1/VCC2), and enable (EN1/EN2) terminals. This construction prevents substrate coupling and ensures >100 dB inter-channel isolation - explicitly stated in the Features list and validated by the absence of crosstalk in characterization curves.
What is the thermal shutdown threshold for the MC33762DM-3030R2?
The MC33762DM-3030R2 activates thermal shutdown at a typical junction temperature of 125°C, as documented in the Electrical Characteristics table under "THERMAL SHUTDOWN." Once triggered, the device disables both regulators until junction temperature falls below the hysteresis threshold (~15°C below trip point), protecting against sustained overload in enclosed or high-ambient environments.
Can the MC33762DM-3030R2 operate from a 1.0 V logic supply for enable control?
Yes, the MC33762DM-3030R2 supports 1.0 V platform interfaces: its EN1 and EN2 pins activate at 900 mV (typical) and deactivate at 150 mV (typical), as verified in the Pin Function Descriptions and Electrical Characteristics tables. This allows direct connection to 1.0 V GPIOs without level-shifting circuitry - a design feature explicitly highlighted in the datasheet's Features section.
