Product details
Overview
MC33762DM-2828RG from onsemi is a dual ultra-low-noise, low-dropout linear regulator delivering two independent 2.8 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-2828RG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel isolation, absence of external bypass capacitor requirement, fast transient recovery in burst-mode loads, and guaranteed 1.5% output precision over −40°C to +85°C.
Technical Context
The MC33762DM-2828RG integrates two fully independent LDO regulators on separate dice, enabling >60 dB inter-channel isolation and eliminating crosstalk in mixed-signal systems. Each regulator features dedicated enable pins (En1/En2) with 900 mV logic-high threshold and 150 mV logic-low shutdown level.
Its proprietary load transient improvement architecture actively detects output overshoot decay and forces rapid return to regulation - preventing deep undershoot during successive burst loads. Combined with 70 dB ripple rejection at 1 kHz and <20 mV line regulation, it maintains stable voltage under dynamic supply and load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V per channel, ±1.5% tolerance at 25°C; ±3.0% over full temperature range |
| Noise Performance | 40 µVRMS (100 Hz–100 kHz); 150 nV/√Hz spectral density at 100 Hz - no external bypass capacitor required |
| Dropout Voltage | 90 mV @ 30 mA; 160 mV @ 80 mA - enables operation with minimal input–output differential |
| Startup Time | 40 µs typical from OFF to regulated output - enabled by elimination of bypass capacitor charging delay |
| Ripple Rejection | 70 dB @ 1 kHz - suppresses switching noise from upstream DC/DC converters |
| Thermal Shutdown | Activates at 125°C junction temperature - protects against sustained overload or poor PCB thermal design |
| Operating Temperature | −40°C to +85°C ambient - qualified for industrial and automotive cabin applications |
Pinout & Package
MC33762DM-2828RG is housed in an 8-pin Micro8 (Case 846A) surface-mount package with exposed thermal pad for enhanced heat dissipation. Pin 1 is GND1, and marking includes "2828" indicating dual 2.8 V outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND1 | Ground reference for Regulator 1 | Must be connected to low-impedance ground plane; separates noise paths from Regulator 2 |
| 2 - En1 | Enable control for Regulator 1 | Active-high: ≥900 mV enables; ≤150 mV disables - compatible with 1.0 V logic platforms |
| 3 - GND2 | Ground reference for Regulator 2 | Independent ground node prevents coupling between channels; improves PSRR isolation |
| 4 - En2 | Enable control for Regulator 2 | Independent control allows staggered power-up or selective channel shutdown |
| 5 - Vcc2 | Input supply for Regulator 2 | Accepts 3.8 V to 12 V input; requires local 1.0 µF decoupling capacitor |
| 6 - Vout2 | Regulated 2.8 V output for Channel 2 | Stable with 1.0 µF ceramic or tantalum output capacitor; ESR-insensitive design |
| 7 - Vcc1 | Input supply for Regulator 1 | Electrically isolated from Vcc2 - supports dual-input configurations |
| 8 - Vout1 | Regulated 2.8 V output for Channel 1 | Delivers clean 2.8 V to noise-critical circuits; output impedance <1 Ω up to 100 kHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A3918DR | Dual 1.8 V fixed output; 12 µVRMS noise but requires 2.2 µF ceramic output capacitor; no load transient improvement feature | Optimized for low-voltage digital cores, not RF analog stages requiring 2.8 V | Select only if system uses 1.8 V logic and prioritizes lowest possible noise over burst-mode robustness |
| NCP1117DTADJG | Single adjustable-output LDO; 42 µVRMS noise; no enable pin; dropout ~1.1 V @ 800 mA - incompatible pinout and functionality | Suitable for cost-sensitive non-critical analog rails, not dual-channel isolated designs | Not a functional alternative - requires redesign for dual-rail, enable-controlled, low-noise operation |
Compared with TPS7A3918DR and NCP1117DTADJG, the MC33762DM-2828RG uniquely delivers matched 2.8 V dual outputs with integrated load transient improvement, zero-bypass-capacitor operation, and independent enable control - making it the only viable option for TDMA burst-mode RF power delivery without layout or firmware changes.

FAQ
What output voltage does the MC33762DM-2828RG provide?
The MC33762DM-2828RG provides two independent, fixed 2.8 V outputs - one per channel - with ±1.5% accuracy at 25°C and ±3.0% over −40°C to +85°C. The "2828" in the part number explicitly denotes dual 2.8 V configuration, confirmed in the official ordering table and electrical characteristics section of the datasheet.
Does the MC33762DM-2828RG require an external bypass capacitor?
No, the MC33762DM-2828RG does not require an external bypass capacitor. Its proprietary low-noise architecture achieves 40 µVRMS noise (100 Hz–100 kHz) without one - a key differentiator verified in the Applications Hints and Electrical Characteristics sections. This eliminates startup delay and reduces component count.
What is the startup time of the MC33762DM-2828RG?
The MC33762DM-2828RG has a typical startup time of 40 µs from OFF to regulated output, measured from 10% of the enable signal rise to 90% of nominal Vout. This fast response is enabled by the absence of a bypass capacitor and is specified in the Electrical Characteristics table under "Output Rise Time".
How is channel isolation achieved in the MC33762DM-2828RG?
Channel isolation in the MC33762DM-2828RG is achieved via physically separate silicon dice for each regulator - a design feature explicitly stated in the Features list. This results in >60 dB inter-channel isolation, confirmed by the separate ground pins (GND1/GND2) and independent enable/control paths.
What protection features does the MC33762DM-2828RG include?
The MC33762DM-2828RG includes thermal shutdown (activates at 125°C), current limiting (100–180 mA typical), and antisaturation protection. These protections are documented in the Block Diagram, Maximum Ratings, and Electrical Characteristics tables - ensuring safe operation under overload, short-circuit, or high-temperature conditions.
