MC33263
Ultra Low Noise
150 mA Low Dropout
Voltage Regulator with
ON/OFF Control
Housed in a SOT23–L package, the MC33263 delivers up to
150 mA where it exhibits a typical 180 mV dropout. With an
incredible noise level of 25 mVRMS (over 100 Hz to 100 kHz, with a
10 nF bypass capacitor), the MC33263 represents the ideal choice for
sensitive circuits, especially in portable applications where noise
performance and space are premium. The MC33263 also excels in
response time and reacts in less than 25 ms when receiving an OFF to
ON signal (with no bypass capacitor).
Thanks to a novel concept, the MC33263 accepts output capacitors
without any restrictions regarding their Equivalent Series Resistance
(ESR) thus offering an obvious versatility for immediate implementation.
With a typical DC ripple rejection better than –90 dB (–70 dB @
1 kHz), it naturally shields the downstream electronics against choppy
power lines.
Additionally, thermal shutdown and short–circuit protection
provide the final product with a high degree of ruggedness.
Features:
Very Low Quiescent Current 170 µA (ON, no load), 100 nA (OFF,
no load)
Very Low Dropout Voltage, typical value is 137 mV at an output
current of 100 mA
Very Low Noise with external bypass capacitor (10 nF),
typically 25 µVrms over 100 Hz to 100 kHz
Internal Thermal Shutdown
Extremely Tight Line Regulation typically –90 dB
Ripple Rejection –70 dB @ 1 kHz
Line Transient Response: 1 mV for DVin = 3 V
Extremely Tight Load Regulation, typically 20 mV at DIout = 150 mA
Multiple Output Voltages Available
Logic Level ON/OFF Control (TTL–CMOS Compatible)
ESR can vary from 0 to 3W
Functionally and Pin Compatible with TK112xxA/B Series
Applications:
All Portable Systems, Battery Powered Systems, Cellular
Telephones, Radio Control Systems, Toys and Low Voltage Systems
