CMOS LDO Regulators for Portable Equipments 1ch 150mA CMOS LDO Regulators No.11020EBT04 BHNB1WHFV series Description The BHNB1WHFV series is a line of 150 mA output, high-performance CMOS regulators that deliver a high ripple rejection ratio of 80 dB (Typ., 1 kHz). They are ideal for use in high-performance, analog applications and offer improved line regulation, load regulation, and noise characteristics. Using the ultra-small HVSOF5 package, which features a built-in heat sink, contributes to space-saving application designs. Features 1) High accuracy output voltage: 1% 2) High ripple rejection ratio: 80 dB (Typ., 1 kHz) 3) Stable with ceramic capacitors 4) Low bias current: 60 A 5) Output voltage on/off control 6) Built-in overcurrent and thermal shutdown circuits 7) Ultra-small HVSOF5 power package Applications Battery-driven portable devices, etc. Product line 150 mA BHNB1WHFV Series Product name 2.5 2.8 2.85 2.9 3.0 3.1 3.3 Package BHNB1WHFV HVSOF5 Model name: BHNB1W a b Symbol Description Output voltage specification Output voltage (V) Output voltage (V) 25 2.5 V (Typ.) 30 3.0 V (Typ.) a 28 2.8 V (Typ.) 31 3.1 V (Typ.) 2J 2.85 V (Typ.) 33 3.3 V (Typ.) 29 2.9 V (Typ.) b Package HFV: HVSOF5 www.rohm.com 2011.01 - Rev.B 1/8 2011 ROHM Co., Ltd.

Recommended operating ranges (not to exceed Pd) Parameter Symbol Ratings Unit Power supply voltage VIN 2.5 to 5.5 V Output current IOUT 0 to 150 mA Recommended operating conditions Ratings Parameter Symbol Unit Conditions Min. Typ. Max. The use of ceramic *2 Input capacitor CIN 0.1 F capacitors is recommended. The use of ceramic *2 Output capacitor CO 2.2 F capacitors is recommended. *2 Make sure that the output capacitor value is not kept lower than this specified level across a variety of temperature, DC bias characteristic. And also make sure that the capacitor value cannot change as time progresses.
