Coeff. Note 1. VIN(MIN) = VOUT + 0.3V DETAILED DESCRIPTION The CM2830/CM2830A family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, thermal shutdown, and short circuit protection. The P-channel pass transistor receives data from the error amplifier, over-current shutdown, short output protection, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal shutdown circuits become active when the junction temperature exceeds 150℃, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120℃. The CM2830/CM2830A switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The CM2830 also incorporates current fold-back to reduce power dissipation when the output is short-circuited. This feature becomes active when the output drops below 1.05V, and reduces the current flow by 65%. Full current is restored when the voltage exceeds 1.05V. EXTERNAL CAPACITOR The CM2830/2830A is stable with an output capacitor to ground of 2.2µF or greater. It can keep stable even with higher or poor ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 0.1µF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground termination is desirable. 2002/01/28 Preliminary Rev. 2 Champion Microelectronic Corporation Page 7 CM2830/CM2830A 300mA CMOS LDO TYPICAL ELECTRICAL CHARACTERISTICS 2002/01/28 Preliminary Rev. 2 Champion Microelectronic Corporation Page 8 CM2830/CM2830A 300mA CMOS LDO 2002/01/28 Preliminary Rev. 2 Champion Microelectronic Corporation Page 9 CM2830/CM2830A 300mA CMOS LDO 2002/01/28 Preliminary Rev. 2 Champion Microelectronic Corporation Page 10 CM2830/CM2830A 300mA CMOS LDO PACKAGE DIMENSION TO-92 (N92) θ A A1 b D A D1 E L e θ θ1 A1 L θ1 e D D1 b E SOT-23-3 (M23) D 3 b1 With Plating c c1 A A1 E E1 A2 b b Base Metal b1 c Section B-B c1 D E 1 E1 2 e b L e1 L1 e θ1 e1 θ θ1 θ A2 A θ2 A1 θ2 2002/01/28 Preliminary Rev. 2 See Section B-B L L1 Champion Microelectronic Corporation Page 11 CM2830/CM2830A 300mA CMOS LDO PACKAGE DIMENSION (CONTINUED) SOT-23-5 (M25) D 5 4 b1 With Plating c c1 A A1 E E1 A2 b b Base Metal b1 c Section B-B c1 D E 1 2 3 E1 e b L e1 L1 e θ1 e1 θ θ1 θ A2 A θ2 θ2 A1 L See Section B-B L1 SOT-89 (M89) D D1 L 5° H E φ1.0 C e e1 A 8° L b b1 C D D1 H E e1 b 2002/01/28 Preliminary Rev. 2 b1 b e Champion Microelectronic Corporation Page 12 CM2830/CM2830A 300mA CMOS LDO NUMBERING SCHEME Ordering Number: CM2830XYZ/CM2830AXYZ (note1) note1: CM2830/CM2830A : 300mA CMOS LDO X : Suffix for voltage output (note 2) Y : Suffix for Temperature Range (note 3) Z : Suffix for Package Type (note 4) note 2: see CMOS LDO Voltage Suffix Table CM2830/A will provide options of A (1.5V), D(1.8V), E (1.9V), F(2.0V), H (2.2V), K(2.5V), M(2.7V), N(2.8V), O (2.9V), P(3.0V), S(3.3V), U(3.5V), V(3.6V), X(3.8V) note 3: Y= I : -40℃~+85℃ (only I grade support for all CMOS LDOs) note 4: Z is single alphabet with or without digits M23 : SOT-23 (TR only) N92 : TO-92 (TA only) M25 : SOT-25 (TR only) M89 : SOT-89 (TR only) CMOS LDO Voltage Suffix Table Output Voltage 1.5V 1.6V 1.7V 1.8V 1.9V 2.0V 2.1V 2.2V 2.3V 2.4V 2.5V 2.6V 2.7V 2.8V 2.9V 2002/01/28 Preliminary Rev. 2 Suffix A B C D E F G H I J K L M N O Output Voltage 3.0V 3.1V 3.2V 3.3V 3.4V 3.5V 3.6V 3.7V 3.8V 3.9V 4.0V Champion Microelectronic Corporation Suffix P Q R S T U V W X Y Z Page 13 CERAMIC/SURGE ABSORBER SHANGHAI,CHINA DIODES LAB HANGZHOU,CHINA CERAMIC/PZT SHINCHU,TAIWAN DC POWER LAB TAIPEI,TAIWAN
