Product details
Overview
SIP21106DVP-18-E3 from Vishay Siliconix is a fixed-output 1.8 V, 150 mA low-noise LDO voltage regulator in TSC75-6L package. It delivers 135 mV dropout at full load, 60 µV(rms) output noise (10 Hz–100 kHz), and ±1.0 % output accuracy at 25 °C. Designed for battery-powered RF systems, it extends runtime via 35 µA ground current at 1 mA load and features auto-discharge via 100 Ω internal NMOS during shutdown.
For engineers reviewing the SIP21106DVP-18-E3 datasheet, SIP21106DVP-18-E3 pinout, SIP21106DVP-18-E3 application, or SIP21106DVP-18-E3 equivalent, key selection criteria include ultra-low noise performance, industrial temperature range support (−40 °C to +85 °C), compatibility with 1 µF ceramic output capacitors, and absence of external POK or adjust functionality-distinguishing it from SiP21107/SiP21108 variants.
Technical Context
The SIP21106DVP-18-E3 employs a P-channel MOSFET pass transistor with 0.9 Ω typical on-resistance, enabling low dropout and near-zero gate drive current. Its bandgap reference (1.2 V) and error amplifier maintain regulation across input voltages from 2.2 V to 6 V and load currents up to 150 mA.
Internal circuitry includes thermal shutdown at 160 °C (20 °C hysteresis), short-circuit protection (330 mA typical), and active pull-down for output discharge. The BP pin accepts a 10 nF bypass capacitor to suppress noise-critical for RF subsystems where spectral purity directly impacts receiver sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±1.0 % at 25 °C - ensures stable core supply for low-voltage microcontrollers and RF ICs without external feedback. |
| Dropout Voltage | 135 mV at 150 mA load - enables operation down to VIN = 1.935 V, maximizing usable battery voltage range in single-cell Li-ion or alkaline systems. |
| Output Noise | 60 µV(rms), 10 Hz–100 kHz with 10 nF BP cap - meets stringent noise requirements for GSM/Bluetooth transceivers and precision analog front-ends. |
| Ground Current | 35 µA typical at 1 mA load - minimizes quiescent drain during sleep modes, extending standby time in portable devices. |
| Shutdown Current | ≤1 µA at 85 °C - guarantees negligible battery leakage when EN pin is pulled low, critical for long-term storage or maintenance-free deployments. |
| Operating Temp | −40 °C to +85 °C ambient - supports industrial-grade reliability in handheld test equipment and automotive infotainment modules. |
| Package | TSC75-6L (1.6 mm × 1.6 mm × 0.55 mm) - ultra-compact footprint with exposed pad for enhanced thermal dissipation on dense PCBs. |
Pinout & Package
TSC75-6L package: 1.6 mm × 1.6 mm × 0.55 mm, lead-free, RoHS-compliant, with exposed thermal pad. Pin 1 marked by dot; top view orientation per Vishay Document 74442 Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control: ≥1.2 V enables regulation; ≤0.4 V disables output and activates 100 Ω auto-discharge path. |
| 2 (GND) | Power ground | Primary return path and thermal conduction node-must connect to large copper plane for junction temperature control. |
| 3 (VIN) | Input supply | Accepts 2.2–6 V input; requires 1 µF ceramic bypass capacitor placed adjacent to pin for stability and line-transient immunity. |
| 4 (VOUT) | Regulated output | Delivers fixed 1.8 V; stable with ≥1 µF ceramic output capacitor (ESR < 0.4 Ω) and no external compensation needed. |
| 5 (NC) | No connection | Internally unconnected-must remain floating; no routing or soldering permitted. |
| 6 (BP) | Noise bypass | Connects to 10 nF ceramic capacitor to ground to filter high-frequency noise; omission increases output noise to ~350 µV(rms). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 60 µV(rms) with 10 nF BP cap-enables clean power for RF receivers and ADC reference supplies without additional filtering stages. |
| Auto-discharge on shutdown | 100 Ω internal NMOS discharges 1 µF output cap in <1 ms-prevents residual voltage from interfering with system reset sequencing. |
| Stable with small ceramics | Guaranteed stability using only 1 µF X7R/Y7R output capacitor-reduces BOM count and board area vs. traditional LDOs requiring tantalum or larger ceramics. |
| Thermal & short-circuit protection | 160 °C shutdown with 20 °C hysteresis and 330 mA current limit-allows indefinite output short without damage, simplifying fault-tolerant design. |
| Low ground current | 35 µA typical at 1 mA load-directly improves battery life in always-on sensor nodes and wearable health monitors. |

FAQ
What is the maximum input voltage rating for SIP21106DVP-18-E3?
The absolute maximum input voltage for SIP21106DVP-18-E3 is 6.5 V relative to GND. For reliable operation, the recommended input range is 2.2 V to 6.0 V. Exceeding 6.5 V risks permanent damage, and operation below 2.2 V prevents regulation due to dropout constraints. Always include a 1 µF ceramic input capacitor close to the VIN pin to suppress transients.
Does SIP21106DVP-18-E3 require an external bypass capacitor on the BP pin?
Yes, SIP21106DVP-18-E3 requires a 10 nF ceramic capacitor connected from the BP pin to GND to achieve its specified 60 µV(rms) output noise. Without this capacitor, output noise rises to approximately 350 µV(rms). The BP pin is not functional in SiP21107/SiP21108 variants-this noise-reduction feature is exclusive to the SiP21106 family.
Can SIP21106DVP-18-E3 be used with ceramic output capacitors smaller than 1 µF?
No-SIP21106DVP-18-E3 requires a minimum 1 µF ceramic output capacitor (X7R or Y7R dielectric) for guaranteed stability across −40 °C to +85 °C. Using capacitors smaller than 1 µF may cause oscillation or poor load-transient response. The device is optimized for 1 µF; larger values improve PSRR but do not harm stability.
What happens to the output voltage of SIP21106DVP-18-E3 during shutdown?
When the EN pin is pulled low (<0.4 V), SIP21106DVP-18-E3 enters shutdown mode and actively discharges its VOUT pin to GND through an internal 100 Ω NMOS transistor. This ensures VOUT decays to <100 mV within 1 ms for a 1 µF load, preventing unintended wake-up or latch-up in downstream circuitry.
Is SIP21106DVP-18-E3 compatible with lead-free reflow soldering processes?
Yes, SIP21106DVP-18-E3 is RoHS-compliant and qualified for lead-free reflow soldering per JEDEC J-STD-020. Peak reflow temperature is rated at 260 °C for 10 seconds maximum. The TSC75-6L package uses matte tin plating and withstands standard Pb-free thermal profiles without delamination or parametric shift.
