Product details
Overview
SIP21106DVP-30-E3 from Vishay Siliconix is a fixed-output 3.0 V, 150 mA low-noise low-dropout (LDO) regulator in TSC75-6L package. It delivers 135 mV dropout at 150 mA load, 60 µV(rms) output noise (10 Hz–100 kHz), and ±1.0 % output voltage accuracy at 25 °C. Designed for battery-powered RF systems, it extends runtime via ultra-low 35 µA ground current at 1 mA load and auto-discharge via 100 Ω internal NMOS during shutdown.
For engineers reviewing the SIP21106DVP-30-E3 datasheet, SIP21106DVP-30-E3 pinout, SIP21106DVP-30-E3 application, or SIP21106DVP-30-E3 equivalent, key selection criteria include dropout performance under 150 mA load, noise sensitivity in RF bias rails, thermal derating in compact layouts, and compatibility with 1 µF ceramic output capacitors without external compensation.
Technical Context
The SIP21106DVP-30-E3 uses a P-channel MOSFET pass transistor with 0.9 Ω typical on-resistance, enabling low quiescent current and no base-drive loss. Its bandgap reference (1.2 V) and error amplifier maintain regulation across -40 °C to +85 °C ambient, with internal feedback for fixed 3.0 V output.
Startup includes active pull-down for fast transient response; shutdown mode reduces supply current to ≤1 µA while discharging VOUT through an integrated 100 Ω NMOS. The BP pin accepts a 10 nF bypass capacitor to suppress noise-critical for RF power amplifier biasing where spectral purity is essential.

FAQ
What is the maximum input voltage rating for SIP21106DVP-30-E3?
The absolute maximum input voltage for SIP21106DVP-30-E3 is 6.5 V relative to GND. Operation above 6.0 V is outside the recommended range and may compromise long-term reliability. The device is specified for continuous operation between 2.2 V and 6.0 V input, with dropout behavior defined at 3.135 V minimum for 3.0 V output.
Does SIP21106DVP-30-E3 require an external bypass capacitor on the BP pin?
Yes, SIP21106DVP-30-E3 requires a 10 nF ceramic capacitor from BP pin to GND to achieve the specified 60 µV(rms) output noise. Omitting this capacitor increases noise to ~350 µV(rms). Larger values (>50 nF) are not recommended, as they degrade startup time and may affect stability due to pre-charge circuit limitations.
How does the auto-discharge function work in SIP21106DVP-30-E3 during shutdown?
When EN is pulled low, SIP21106DVP-30-E3 enters shutdown mode and activates an internal 100 Ω NMOS between VOUT and GND. This discharges a 1 µF output capacitor in under 1 ms, eliminating residual voltage that could cause latch-up or false wake events in downstream logic. The resistor value is fixed and not user-adjustable.
Can SIP21106DVP-30-E3 be used with ceramic output capacitors smaller than 1 µF?
No-SIP21106DVP-30-E3 requires a minimum 1 µF ceramic output capacitor for guaranteed stability across -40 °C to +85 °C. The datasheet specifies stability with "6 nF/mA" capacitance, equating to ≥0.9 µF at 150 mA; 1 µF is the validated minimum. Using smaller values risks oscillation, especially with high-ESR or temperature-sensitive dielectrics like Y5V.
Is SIP21106DVP-30-E3 still in production or available for new designs?
SIP21106DVP-30-E3 is End of Life per Vishay's notice: last purchase date was 31-Dec-2014. However, Aetrix Electronics maintains legacy inventory with traceable sourcing and supports ongoing production programs via lifecycle availability coordination, including obsolescence mitigation planning and cross-reference guidance.
